Finger Strengthener,4 Tension Adjustable Hand Grip Exerciser Ergonomic Silicone Trainer for Guitar,Piano,Trigger Finger Training, Arthritis Therapy and Grip, Rock climbing (AHF-03)

This is well made and designed strengthener for hand and fingers. Mostly for improving strength and dexterity for playing guitar and other string instruments. The bottom bar has a textured finish which makes slipping away from the thumb nearly impossible. Takes a bit of practice to get the technique but when you get there, you will feel the benefits fairly soon.

Works very well, I got it for my father who needed it for his hands , its a great buy

So I have been using for the past couple days while I work. It is the perfect thing if you use fidget toys and play a kisic instrument. As far as the actual purpose of the product, it is alright. I notice my pinky getting noticeably stronger each day, but this device leaves only a tiny amount of adjustment. It is a good starter, but I will probably need an upgrade soon. Especially great if you play bass guitar!

I exercise with this little gadget on my left side. My thing is a stronger because I have a trigger finger and I just didn’t have to get an injection because I exercise with this little gadget. It was really good.

It's ok. Does what it is supposed to do, but the build quality is questionable.

Beginner guitar player. Using it to strengthen fingers. So far it's been useful.

Nice and adjustable so you can’t set a tension to help strengthen your fingers

The adjustment from 4-7 pounds is not even noticeable. In fact I don’t think it even works. However I needed to strengthen my pinky finger specifically for guitar after a serious injury some years ago so this works as a rehab device for me. It does just that and that’s all that matters. I only have four stars because the adjustment is not noticeable at all.
