Quality Product
Very well built and works exactly as advertised. This will really give your forearms a workout.

Unexpectedly impressed and already feel a difference
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 thatThis 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.

Cool device, but doesn’t compare to the Sidewinder Pro
Great device for forearm development and pump. This is like a cheaper version of a Sidewinder Pro. Harder to adjust and action not as smooth. Still a 5 star product, but only because the Sidewinder Pro is 6/5 stars and every other wrist curl product I’ve ever used is garbage.

Maybe the best exercise equipment I’ve ever used.
This is one of the best pieces of exercise equipment I’ve ever used.I’ve never gotten a better pump. Previously, I’ve used a handle/rope with weights for forearms for years. That doesn’t come close to the pump I get from this thing.Well worth the money!

Dynamo for forearm size and grip strength
I have been using the Dynamo for a little over a week and I have always gotten some amazing results in my grip strength and my forearm size in general in the short amount of time that I have been using it. The fact that it’s so portable makes it so convenient to be able to workout my forearms and my grip whenever I want. I literally probably use the Dynamo 4 times a day and every time I use it, my forearms just feel such an amazing pump. I would recommend this product to anybody looking to enhance their grip strength and who are looking to really get a killer workout for their forearms. I love the Dynamo!!!!

Very “gritty”
Seems to be effective, but cheaply made. Rotation alternates between smooth and very “gritty.” You can tell it wasn’t made in the USA. I hope it will last, but we shall see.

Good Durable Equipment
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.

As advertised.
Good tool. You don’t need weights to exercise
Shereif Dewedar –
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
