GRIPZILLA Dynamo Forearm Strengthener and Wrist, Comfortable Grip and a Durable Design Roller Perfect for Men and Women - Ideal for Hand, Wrist, and Forearm Strength Training, Workout - Wrist/Arm Builder

This product has definitely made a difference in my forearm strength. What I like: usable straight out of the box Solid construction, I expect it will last a while Adjustable enough for me OR my ten year old son to use it for hockey training Comes with a travel case, not a pro or a con, just interesting. Improvements: There’s no way to measure which difficulty you have it set at, so if different people are using it, it can be tricky to get it dialed back in. Overall, I’d recommend

This thing is the real deal. Anybody from grandma to gigachad could get a good workout from it. Its light, its small enough to put anywhere and versitile enough to work anything from shoulders to finger tips. One draw back, it has sensitive adjustments. After fiddling with it for 30 second though you'll get the hang of dialing in both knobs for your ideal setting.

Great device. Have weak wrists and within a few weeks can tell they are getting stronger. Helping with my gym workouts my grip has improved

It feels well made and you can carry it almost everywhere, the only issue I have is that it is difficult to adjust the resistance, it is either really hard or really loose, so if you are a beginner you night have problems adjusting to an intermediate resistance

This is a good addition to a home gym. I use it to warm up my hands, wrists and forearms prior to weight training. My only complaint is that the resistance adjustment keys are too prominent. They should fold down when not in use to allow more clearance for the forearms. I'd still buy again.

Crazy stuff! 20 seconds, my forearms are worn out! Can't wait to see how much it will do to my forearms in a month! Feels very durable and it adjusts well.

excellent forarm builder. you can control the resistance, easily portable. it also builds hand strenght. if you are seeking a solid durable forearm equipment you cannot go wrong with this gripzilla.

Great product, incredibly solid and a beautiful object in its own right. I recommend trying it with the N-Gage grips to make it more pleasant to use on the palms.

The rotation movement is not smooth enough and the grip is very tough and you will need to wear a gloves if you are planning to use it for a long time, but for ten or twenty rotations you will be ok

Solid product - use it while watching tv

Excelente resistencia, buen producto

Showed black hardware but got gold hardware instead. Movement somewhat smooth but not as high quality as expected. Returned.
