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

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

It works. Very simple. Your forearms feel the fatigue letting you know they are underdeveloped

Honestly, this thing is really well made. It’s probably “overbuilt” for its purpose, but I love it. As a former kick boxer, having strong arms and wrists is, of course, very important. I could tell how well it will work in the long run from the very first use.

Originally ordered this and got a hand gripper tool in the box that this was supposed to come in. Clearly someone switched the items out. I immediately ordered a replacement and finally got the actual product and it’s fantastic. Underrated for therapy on the hands and wrist especially if you work with computers all day.

The price is high, but seems to be good quality. My arm wrestling team and I get a good forearm workout/pump with this tool. Very similar device to the one Denis Cyplenkov made/uses. The tension can be adjusted to burn you out quickly or set where you can “comfortably” do 60 seconds. I’d recommend the Gripzilla Dynamo for arm wrestling training and forearm building.

Really good product I really recommend

Yeah. Just yeah. The burn is legit. The pump is nuts. Watching the muscles strain and the veins pop out from such a simple device is straight awesome. I’m 56 and active and have bad carpal tunnel on one side. Twitching pinkie, can’t open lids. All that This has already made my grip strength grow and I kinda feel like after a few sessions that carpal issue is somewhat minimized. As one who isn’t afraid to call out snake oil. This one isn’t. I’ll recommend to anyone needing stronger grips and forearms but just know it works other groups too.

Outstanding product. So different than other grip strengthening devices, including Captains of Crush. The video an are super helpful in the work out plan. .

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
