    Well made product and seems like it will work well.
  

*by K***5 on Reviewed in the United States on May 29, 2021*

So far, so good!  I recently have gotten back into playing guitar and working on building calluses.  Due to neck strain, I have to take a break ftom playing and worried about losing what calluses J had built up.I found this tool by accident and I’m glad I ordered it.  It’s a bit smaller than Zi thought it would be but that’s OK since I have small hands.  It’s very sturdy and well made and feels like it will work well for building up my calluses.I will update this review after I’ve used it for a while.

    Actually Works!
  

*by M***E on Reviewed in the United States on June 3, 2022*

It's sad that I have to use one of these to keep my finger calluses firm because I don't have the time to play guitar as much as I would like to.  But, when I do get to play, I don't have sore fingers which is why I bought it.  It works well, would buy again.
