The item looks strong enough. It works well and after one day of use I can already feel my 4th and 5th finger benefit from it. Unfortunately it doesn't seem to be adjustable like other brands which are also more expensive . I opened it and I can see that the inner buttons have a lighter spring while the outer buttons are stronger . So you could always swap them around and here it is the "adjustment" . For the price it's ok. It might not work for someone who doesn't have much strength. Perhaps at the beginning they can press it half way until they gain some strength.

I received this yesterday and began to exercise with it, after 5 minutes the ring finger button was fired acroos the room leaving me with what can be seen in the photo. The build quality is not very good, the palm pad just slipped off too. Spend a bit more money if buying one of these items.

They don't come with instructions but are easy to use & seem logical to use. They move easily, would be nice to have ideas on how to use it. It is just one so if you want to use for both hands you'll need to bye 2.

It was great for the first few days until the two middle pistons/buttons came flying off and after finding the buttons and springs I could not re-assemble them so now its completely useless so be aware if you buy this.Update: The very helpful customer service representative informed me that this is uncommon and are sending another unit out to me. I have adjusted my review in light of how quickly the company were to address this issue. When the new unit arrives I will update this again addressing the reliability.

Good product, worked well for me in strengthening my fingers for the ol'guitar playing.

A good well made basic finger exerciser. I bought this to help improve my guitar playing by increasing my fretting finger strength and movement accuracy, particularly the 3rd and 4th fingers as these are the weakest and seem to be more difficult to control for me. It's an easy tool to carry around and use during the day at work when I am away from my guitar.
