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

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

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

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.

Quality product, like the ones that have the plate dangling off but much more portable.
