"This is the next big innovation in golf. Why hasn't anyone thought of this before? As soon as my customers hit a club with a JumboMax grip on it they are amazed at the results!
These grips have completely changed my outlook on grip fitting. While being able to hold the club with a lot less tension, my customers are able to release the club more easily, therefore allowing them to hit the ball longer and straighter.
I truly believe that JumboMax grips are going to have as big of an impact in the grip category as graphite shafts and titanium clubheads have had in their respective areas. This one is a game changer in the golf industry!
In the 3 short months I have been stocking them, they have become my #1 selling grip!"

"As a longtime golf writer I have seen enough product samples over the years to fill a warehouse. Few live up to the hype. But Jumbomax grips are the real deal!
The feeling on your hand is so natural, and you instantly can swing faster and with more power. Even with a thicker grip, and contrary to popular thought, it was easy for me to hit my normal high draw with my driver.
It's one of those products your pals will say "What the heck is that?" But when they try it on your club they will be convinced."

"I cannot remember ever being so impressed by a company and their product before. Nice web site and fantastic customer service aside, the reason I will keep coming back is the fact that your grips have made a profound improvement in my game.
All of my fitting sessions have indicated that I should be using a + 1/32 sized grip. Despite help from numerous local Pros, my grip pressure has always been an issue that has adversely affected my game.
Although I am still experimenting with my normal overlapping grip and the baseball style, I can say without reservation that I am seeing significant and consistent improvement in accuracy and distance with both.
I cannot thank you enough. "

"I had been hearing the "buzz" regarding JumboMax grips. I was interested in trying them out. I received my grips in the mail; but was a little reluctant to putting them on my clubs. I was hitting my driver OK and didn't want to change too much. It wasn't until I won a Cleveland Driver during a golf outing that I put the JumboMax grip on the club.
I took the driver on the range and hit it well and liked the consistency of the drives. The grip felt so comfortable in my hands, and my confidence hitting my driver grew. I have since put a JumboMax Grip on my Nike 3 wood. Those two clubs in my hand feel so good it now, feels strange to handle a normal grip.
This is a great product and one that must be tried!"

"I installed a full set of large Jumbomax grips. During this, my 2nd season, I notice: grip, swing and overall golf game improvement, under varied weather conditions."

Hey Guys,
"All I can say is WOW!!!!!!!! I have been fighting the hooks forever. I walked past your booth and started talking with Corey. One thing lead to another and bam. I was consistently hitting the ball straight down the middle with NO HOOK. I put the large grip on the new driver I bought and my buddy put it on his driver as well. I will give these grips 2 thumbs up."
Thanks again,

Mike,
"Just completed my first test of JumboMax and they are awesome. I really like the feel of the club, much lighter and a very smooth feeling when swinging. I tried my Driver, 3FW and 6 iron first as a test, after only one small bucket I am having my whole set switched to JumboMax. Not sure if I gained any distance, but ball striking was better. I always used an interlocking grip before, but I am trying an overlapping one to start, still experimenting with that....
Overall A+++++++++++++!!!!"

Hi Mike:
"I met you at Arnold Palmer C.C. in the Villages. I am the guy that came into the Academy at the end of the day and had the staff and you put a grip on my driver.
I played eighteen holes with the new grip and I can't believe how well I played!!!!
My plan is to have the rest of my clubs regripped soon.
One of the members of our foursome, who was playing with his regripped driver, played the best he has played all fall and winter.
Thanks for being at Arnold Palmer and introducing us to your new grip!!
I have already started spreading the word!!!"

Corey,
"After having played a few rounds with the new grips, I can tell you these are the best grips I have ever felt. It has brought my game to a whole new level.
I am driving the ball better than ever, did not slice one drive in my last round. In fact, the first time I went out to my 9 hole course with the new grips I shot a 42 (I average close to 50 over the past 4 years).
I played yesterday in a 2 man scramble and my partner was so impressed with the way I played he wrote a poem:
There was a man named John who was funny,
That often played golf and was crummy,
He bought some new grips,
And gave it some rips,
And now he took Tom and Mike's money.
I am telling everyone about these grips so my next questions is how do I become a sales rep? Corey thanks for turning me on to the JumboMax."

John sent us this update about 2 weeks later...
"Just wanted to let you know how my golf game continues to improve. Yesterday, I shot my best score ever at my 9 hole course — 39 (3 over). A couple of weeks ago as I told you, I shot a 42.
This is all after years of averaging in the upper 40s/low 50s. I have been telling everyone I know about these grips. They feel great.
Your sales should be increasing.
Thanks again,"

Mike,
"Playing with a group of 16 on Saturday we all ended up standing on the second tee box together due to very slow play ahead (mixed tournament).
The honor was mine and I stuck one straight over the pin to 15 feet... well, they nearly tore the club from my hands and proceeded to pass it round the whole group to see how big the grips felt.... all sorts of theories were formulated as to what it does and does not do to the golf swing... funny they were more inclined to credit the grips than little old me :)
Thanks again,"

"I just wanted to say what a great invention your product is. I just played my first full round and once I let myself trust my grip it was just like the first shot I hit at the demo yesterday.
For an average golfer these are an incredible help."

Good Evening Mr. Kachlik,
"It was a pleasure meeting you at the Whisper Creek Golf Club. You introduced me to your product and I decided to have my entire set of clubs re gripped. I played nine holes the next day and shot par.
Thank you."

Hey Mike and Corey,
"These JumboMax golf grips I recently got on my clubs are amazing. I used to not be able to hit my driver more than 100 to 150 yards tops and they'd be all over the course and rarely on the fairway. But now since I got these new grips I hit my driver 200-250 and 9 times out of ten its right down the center of the fairway. It's become my favorite club in the bag.
As for the irons, I have more control and consistency with my shots, as well as the added distance. I've easily been able to drop a stroke a hole with these clubs. Definitely the best golf purchase I've ever made. The best part of these grips though is that it makes golf fun to play again."
Thanks guys,

"You may hear from Corey but thought I'd let you know too.
After the introduction to your grips at the Par 54 outing in Elgin, I asked Corey to try 3. Back at once for the rest this week.
Regard them as my best birthday present to myself! Besides the comfort and confidence, it's the best "feel" for where the club head is in years."

Dear Mike;
"On my recent golf trip to Florida, my buddies kept on saying, “It’s just not fair!” I told them, “You could have bought some grips for yourself, so stop crying about it and get some.”
Thanks Mike for the technology!"

Hi,
"Can you tell me what size grips I ordered about two weeks ago? A friend of mine loves my new grips and wants to order some, but I can't recall for sure what size I ordered.
Best golf product I ever bought!"
Thank You,

Dear JumboMax,
"Just played my first round with your grips and I absolutely think they're wonderful. They just feel so much better in my hands. My 91 year old father, who still plays, picked up one of my clubs last week and immediately said that he wanted these on his clubs! I ordered him a set this evening.
I use the Moe Norman Natural golf grip and set up, and these grips are perfect for getting the club gripped closer to the base of the fingers and more toward the palm. Very comfortable, less grip pressure and does NOT impede the release in any way.
Thanks. I'm looking forward to an enjoyable and improved golfing season."

Hey Mike,
"I've been playing with your grips on my driver and 60 degree for about 12 rounds now. I switched to your recommended 10 finger grip on round two and things improved. I've hit some of the longest drives I've ever hit with it. I'm 49 y/o and a 8 handicapper and draw the ball. One word describes it. "Mash". I have more confidence with the grip to go ahead and mash it.
I love the feel of the grip on my 60 degree around the greens.
Amazing that a $10 grip has added 15 to 20 yards to my drives."

Dear JumboMax,
"I have golfed for 35 years. Through that time, my most consistent club has always been the 7 iron, 160-165 straight and high. So when I had hip replacement surgery what I discovered is that I had lost a full club length, maybe more.
The 16th hole at the Elgin Country Club in Elgin, Illinois is a pretty little par-3, over water to a thin green that widens at both ends. Precisely 165 to the center. For the last two years, my 7 could not carry so I learned to adjust my 6 which was never as accurate. Today, however, the 1st time out this year, without ever going to range to try out these new grips, without a practice swing, without using my 7 once the whole day, I hit my tee shot 165 to the dead center of the green. Flouting all golf etiquette, I dropped another and 165, a 3rd and yes, 165. Take that Tiger! To me, no other explanation other than my new grips by JumboMax. I got my 7 back.
I got the club length that I thought I had lost. I couldn't be more thrilled.
Worth every penny!"

Well Mike,
"75 degrees and sunny here today so I had a chance to demo the clubs with your JumboMax grips.
To be honest, I was more skeptical than optimistic that I could make them work. After playing around a while, I hit a sweet spot with them. I bought a jumbo bucket and after hitting 50 balls with the JumboMax gripped clubs, I couldn’t go back to skinny! It just kind of hurt.
I’m converted! Being on the eternal search for “Ah-ha!” moments, your product definitely fits this criteria of instant enlightenment. I loved the feel. And, I couldn’t help but notice the lack of sore wrist and elbow after hitting a jumbo bucket of 500+ balls. I’m sold.
I think I’m going with the JumboMax medium. They seemed to work well for me. So now, how soon can I get grips shipped to put on my clubs? How did I last this long without these? And do I share this secret weapon with my golfing arch nemesis?
Another converted soul,"

Mike,
"Since I put JumboMax grips on every club in my bag (except my putter) I have enjoyed golf so much more! I'm still working on getting my handicap down, but the grips have been such a wonderful improvement.
I know its hard for some people to accept a new approach to golf but the JumboMax Grips are the greatest. I now have a feeling of complete control of my clubs without having to grip the clubs so tight. I now play without a glove and can feel contact on the ball so much better.
Some of the shots I have hit with the new grips I never thought I would be capable of.
Once again, thank you for introducing me to JumboMax Grips. They have made the game of golf enjoyable for me."
Sincerely,

Mike,
"I have been using JumboMax grips for about six months now and I love them. I first tried them during a charity scramble event that I played with my Brother-in-Law. I hit a few shots on the practice range and was interested enough to want to try them during the outing, since there wasn’t much pressure to perform in the scramble format. I only tried the driver and fairway woods that day but I fell in love with them.
I very quickly became comfortable with the (JumboMax) grips because it felt much more natural to me than the standard size did. And, since my hands were much more comfortable, I was able to better control the club through my entire swing. With better control came more confidence and I believe increased club head speed at impact. The result has been much longer and straighter shots.
I have always been able to hit the ball hard but not with any kind of control. So, I always had to sacrifice distance for control. Well, not any longer. I can now accelerate the head of the club through my swing much more than before. And, I still have the control that comes with the forgiveness!
SInce then I have had my entire set regripped with JumboMax Grips and I'm really looking forward to the upcoming season!"

Dear JumboMax,
"I just wanted to send a quick email to thank you for a great product. My husband used his club with the new grip today and was VERY pleased. He was becoming so discouraged at not being able to grip his driver due to his arthritis. Again thank you for developing a product that will allow many more years of enjoyment."
Sincerely,

Mike,
"I purchased the XL and L version of your grips and have the XL on my drivers and the L on my 3/5 woods.
Absolutely swear by them as they really prevent me from going left. I am known to hit some power draws that just snap, but with your grips I have extreme confidence on the tee and fairway.
I have always been a long ball hitter (280 - 300 driver / 170 8- iron) and swing very aggressively - but with your grips it just seems to calm my wrists down and make me much more consistent.
Thanks for the grips and I will be purchasing more soon."

Update from John:
Mike,
"Great grips and I will probably end up getting the large for my 6/7/8 irons...oh by the way - my kids golf instructor was amazed as I nailed my 4-hybrid with your large grip 230 yards to about 8 feet for birdie to take the hole from him.
Thanks again for the advice and I look forward to doing business with you again...and I passed your info on to everyone I know - they look at the grips and laugh until they see how I play...
Funny how I spend a fortune on my (brand name omitted) Irons and I probably could have just bought your grips to improve my game...
Will keep you posted on my progress..."

Mike,
"Here is an update after playing 3 competitive rounds with all the grips on my clubs.
Thursday 40 + 38 = 78 with 1 four putt and 2 three putts on the back nine along with 2 birdies. As you can see I hit all nine greens on the back and 5 on the front for 14 greens in regulation. I hit 13/14 fairways. On number 14 I hit a 7 iron from 156 that hit the pin stopping 4 inches from going in. That is the closest to a hole-in-one that I have had in forty years since the one and only one I made when I was 18 with a 7 iron.
Saturday 44 + 37 = 81 with 2 penalty shots and 2 three putts. When we teed off in the morning it was 40 degrees with a wind chill in the low 30's. In South Florida we do not get these conditions very often so it was very difficult especially with carpal tunnel to hold the club or even feel my hands. Since I also have a mild to moderate form of Raynaud's Syndrome in my hands when the temperature falls below 50 degrees the blood flows out of the hands leaving them very cold and numb. Considering the conditions I felt 44 was not that bad. It warmed up to the low 50's by the start of the back nine. I was able to sink 3 birdies but had the 2 three putts and 1 of the penalty shots on the back nine. I hit 12/14 fairways but only 9 greens, seven of them on the back side. With the old grips I would have easily shot 85 to 90+ considering the conditions at the start of the round.
Sunday 38 + 37 = 75 with 1 three putt. This is a personal best for me going back over the last 5 years. The main difference between Saturday and Sunday was the temperature as it was in the low 50's at the start of the round and warmed to the high 60's by the end of the round. I hit 13/14 fairways and 12 greens.
One of the nice benefits of the grips is an improvement in my short game. I use to be a poor bunker player getting up and down from the bunker maybe 1 out of 10 time if I was lucky. I would leave it in the bunker or just barely get out about every fifth bunker shot. Over the last 3 rounds I have had 10 bunker shots getting up and down on 5 of them for 50% save rate. In all 10 bunker shots my longest putt was 5 feet so you can see a better putter would have a higher rate of bunker saves. Needless to say I am probably considered a good bunker player now. The grips have also improved my chipping and half wedge play under 80 yards.
My confidence in my ball striking has doubled. This has taken pressure of my putting as I used only 30 putts on Sunday. In my last 27 holes in the warmer weather I have shot 37, 38 and 37 with 3 three putts and 1 penalty shot. This is the most consistent I have played in over 10 years. These grips have made the game fun again. Thanks for creating these grips. Everyone who plays golf and has any problem hitting the ball with regular grips should try these grips."
Sincerely
John Jordan
