2 Pieces Finger Expander Finger Trainers Multifunctional thumb Expansion Guitar Stretcher Portable Musical Instrument Accessories for Guitar Bass Ukulele Piano Saxophone Beginner

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.

I couldn't get it to work for me. I have average American fingers. If you have small(skinny) or child size fingers it may work well for you. Couldn't return it so threw it away.

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.

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.

Nice idea, but … I am an adult male. My knuckles will NOT fit through the finger holes on either of the devices, so it doesn’t work for me!

Good product

The item came with no instructions on how to use it. My fingers are really too larege for the holes on the big one.

I ordered one and had it replaced. I was hospitalized and not able to return the first one. The second one broke right after the return.So I’ve been charged for two pieces of junk! I will never buy from this buyer again!
