Really easy to use, great variations for different grip strength and very simple to progressive overload on. Really effective! 

Really good to strengthen your grip and forearms. I had been struggling to lift heavy due to a weak grip but I have been using this for a few weeks now and have been able to hit PRs in the gym because it has increased my grip strength. However when you set it to above 30kg, it can sometimes make an annoying loud clicking noise.

This is a great little tool for when your sitting at home just passing time. For some people the settings on this may be too much or for people like myself, the maximum setting still doesn’t feel like much but you still get a great burn especially in the forearms. This strengthner starts at 10KG resistance all the way to 40KG. The reason I added this little piece of kit on to my last protein order was because I wanted to give my forearms a pump and increase the muscle mass around my lower arms and it’s great for the exact purpose. I’d recommend negatives when using this as you’ll feel it a lot more, so slow motion releasing will benefit.  My only criticism is the build quality. It makes a lot of noise in the spring and doesn’t feel like a quality made product but still does the job exactly as you’d expect. All In all it’s a decent little tool, and you’ll definitely benefit from having it rather than not. 

Makes noise when you close the grip, but what I really like is that no matter what strength you set it at, the grip width will not change enabling you to get a good range of motion from the start, decent what the price I got it at

Only one important thing about the product - looks and feels pretty strong to me. Overall great product!

Great product, easy to adjust. I am positively suprised

Excellent product, good quality. I’ve ordered all my products from Myprotein.

I don't understand why nobody has left a review for this item yet I just received it today and you can drop the tension to around 20lb and you can up of to 90lb! That is insane! That's 40kg of tension that you're trying to press together with your hand! I know that doesn't sound like much but believe me I tried it and it is very hard! Exellent product for anybody that has weak grip when they're trying to lift them hard to grasp heavy weights! It works your forearms too which is always a good thing!
Goes Well With:
Anybody that feels like they need to improve their grip or people that want to work their fore arms a bit any age (within reason) any gender this item is great for all! 10/10
