Dear Amazon.com Grip Enthusiasts,I really enjoy this MummyFit Death Grip Hand Strengthener. This thing is built like a tank. When you hold it in your hand you notice its quality, beauty, and power. Even the easiest setting is difficult for me to close more than just a few reps. One cool feature is the "clickers" on the bottom of the two handles. These ensure you are closing the handles together; the gripper clicks every time you complete a strong repetition. I noticed the clicking becomes quieter when I have fatigued. This is because I am using less force for each concentric rep. For example, I can close the handles together to make the Death Grip click hard with my right hand. On my left hand, however, it only makes a faint noise and I realize how much weaker my left hand is to my dominant one.Another cool feature is the easy to adjust tension "knob." I have a cheaper gripper, "The Super Human Grip" Adjustable Grip Strengthener from Core Prodigy. While I love it, it requires me to manually adjust the tension knob and then physically move the coil spring to one of its four settings. I then have to re-tighten the tension knob. It is a pain. However, this won't happen with the Death Grip. All you have to do is turn the tension knob and it automatically rolls itself to the next resistance setting. W stands for Weak and to lower the resistance (unless its already at the lowest setting - which it will be when you receive it in its original packaging) you turn the knob to the left. S stands for Strong and you turn the knob to the right. It is that simple!This thing can crank up to an unbelievable resistance, similar to a Captains of Crush 1.5 gripper (155 lbs). The heavy duty thermoplastic material is going to hold up for a lifetime. It comes with a lifetime warranty just in case something happens to it. There are grooves on the outside handle to better grip this device. I have personally found wrapping the first, inner handle with tennis racket tape or putting a piece of soft foam over it will greatly reduce the occurrence of scrapes to the soft tissues of your hand.Finally, their customer service is excellent. Someone from the company both answered my question on Amazon.com below as well as through my personal e-mail account in a matter of hours. Overall, this product will provide me with years of gripping pleasure and I hope to one day close the Death Grip for 3-5 reps on the max setting. When this is the case, I'll be able to crush coconuts with my bare hands!Enjoy.

When I was searching for grippers I wasn't sure what tension range I needed and this product solved the problem right away. You can adjust it anywhere from 55-154 pounds with a slide of a dial and it also has the kilogram conversion on the opposite side of the gripper. This range of tension is perfect because it'll help you increase your strength gradually instead of having to jump up 50 pounds with an individual gripper. Plus you will have the ability to train the hand and forearms for strength and endurance.The price is fair for an all-in-one solution and there's no clutter to be had from having multiple grippers. It also features a basic grip strength routine and explains how to measure your maximum grip strength.Other strengths include:*Durable feel*Great designSo far I haven't had any problems with the product and once I graduate from this gripper, I hope they'll have a product with a higher tension range to help further my gains.

Overall, I think this is a very good product for building grip strength. It is the most advanced grip exerciser that I have owned.In my opinion, here are the pros. I really like the ability to adjust the tension. I can warm up at lower resistance and then increase it for a good workout. The fact that it is silent is a great plus as I can use it during meetings without disturbing anyone.There are also a few areas of improvement that I wish this product had. You have to increase the resistance to get a wider grip. The grip at the lower weight is pretty narrow for large hands. If you tighten the resistance, the grip width is great, but it becomes too difficult to actually use (realistically). The spring does have a 'spongy' feel, in that the resistance is not consistent throughout the full range of motion. It is much easier to squeeze the first 50% (give or take) than the final 50%.I do feel like the quality of the materials is there. The product is sturdy and I believe will last a LONG time. The price is considerably more that other options out there, but I think in the long run this exerciser will be around for the long haul.

New update, now 4.2025 and still functions as they did brand new in 2019. Worth every penny.Update: May 2nd 2020. I've been using these almost everyday since my purchase 4-2019 and they still work insanely perfect like brand new!! Very excellent product with absolutely no regrets!!I bought a pair of these in April 2019 and use them almost everyday. Everyone comments on how huge my forearms are. I do lift weights as well, but I don't have any other specific forearm workout regimen. A couple of years ago, I was breaking one hand/forearm exerciser every 2 weeks not through abuse, just using them as they were advertised. I would return them back to the Big 5 store I purchased them from for $20 bucks a pop. After the 5th return the manager told me he would not warranty any more. Long story short, I don't shop at Big 5 any more. I found these on Amazon last April and have been using them ever since. These are excellent quality. Yes, they are silent as well. The other worthless ones creaked with every squeeze until the springs finally broke. This is a product I highly recommend!! AND!! THEY ARE WARRANTED FOR LIFE! You probably won't need to ever return them; I haven't had to yet and they still feel assolid as the day I bought them. You won't find a better quality gripper/builder with that warranty. Booooo on Big 5! Yeaa on MummyFit!
