Review: Better than expected - These were better than expected. Both devices have moveable finger holes. One is in a rigid frame, the other has the finger holes attached to a bendable metal rod, covered in a black rubber type of substance. These things aren't magic, but tools that can help you exercise and stretch your fingers so you can hit those big wide chords. I'd recommend researching how stretch the fingers and how to use devices like this. Bad technique will give you bad results.
Review: simple but so effective ! - I have seen many reviews and videos hating this device, but none of them are using it correctly. I put it at the tips of my fingers, the the rings spaced equal distance apart opened as far as they will move. then try to make a fist, you will feel a proper stretch. after a few minutes I could feel the difference in my playing after a few days of this I was able to reach 2-3 frets further than before with ease.

### ⭐⭐⭐ Well made but not for grownups
*by R***A on November 12, 2021*

I wear medium size gloves that should put my finger size in perspective. I use the white rings on the black stick and do get a good stretch of the fingers. The black frame with the rings is good concept but only my pinky would fit in them. That was a big let down for me. The product concept is appealing but gets 3 stars because of the size.
