MummyFit Best Grip Strengthener And Adjustable Hand Exerciser

The first thing that I noticed when I used this grip strengthener for the first time was the strong construction and the quality of the material. My other grip strengthener was with a spring that you stretch out and that made some scary sounds. Because of its construction this one seems a lot safer to me. It is also very easy to change the level of resistance; in takes only a few seconds to change it. The biggest advantage this grip strengthener has over others is for me the great range of resistance levels you can choose from. For most people this is probably the only grip strengthener they will ever have to buy.

This hand grip is amazing, it is more harder even that Captain of Crush gripper 2 with 70 kg. Handles are soften and sturdy to prevent callus and spring are not squeaky. I have no doubts to recommend this product.

Super

I have been purchasing stuff on Amazon for a long time now. Never have I ever bee scammed by a product/item.This grip was the first scam I encountered on Amazon. The item came in a box much smaller than its original packaging so the original was bent and deformed. Upon opening the original packaging, I was surprised to see that it was clearly a used rather than a new item! it had scratches and red coloration. Also the logo that appears in the photo does not show on the item which suggests it's nothing but a fake copy.Very bad experience. I will buy things that I can see and test from now on .. No more Amazon for me.

It's not anywhere as strong as they claim it is. Even on full strength it doesn't offer as much resistance as my weaker 40kg grips. This claims it offers up to 70kg, it does not.

Je l'utilise depuis maintenant 2 ans et rien à déplorer, il est génial ! :D

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.

- Grip quality acceptable but not the best, when using you would notice the handle slightly not align (slight twist) when compress because the pivoting manufacture in a way no strong enough...if the handle don't twist when compress it would be perfect.- Gripper should always tension at the initial starting point there is where our weakest position is so that more muscle fiber can be recruited from the gripping movement. No point tensioning when the grip is at its strongest position (near grip) because lesser muscle group will engage and it defeats the purpose. Even if we adjust higher intensity the tension is not consistent from Point A to Point BVerdict: 8/10

Love this forearm builder. I had an accident where my right forearm suffered a severe wound, causing an eight inch long cut and all the way to the bone. I lost most of my forearm mass (from 17 1/2 inches to 14 inches) during the months I was unable to use it. When I could begin exercising it again I could not do forearm curls as my range of motion is now somewhat restricted. I had a couple of old "squeezers" lying around but I soon outgrew their resistance and I had forgotten how uncomfortable they were to use. I was about to buy a stronger set with more comfortable grips when I ran across this bad boy.What attracted me to it was that it was adjustable from 55lbs up to a whopping 154Lbs! But it's so much more than that. It's incredibly strong (not the cheap plastic I feared it would be) composite material, extremely comfortable even for big hands which tend to overlap the ends, and remains comfortable even when you use it upside down to work the extensor muscles and the brachioradialis. You increase of decrease the resistance easily and as incrementally as you like by simply turning a smoothly turning dial clockwise or anti clockwise. My forearm is up to 17" again using this wonderful tool three times a week for twenty minute, high rep sessions for 4 months! I also use it on clients with arthritic hands on the lower settings and has done wonders for their grip strength. Thank you MummyFit, I owe you big time!
