### ⭐⭐⭐⭐⭐ Does the bloody job
*by M***L on June 22, 2025*

Pretty pretty pretty good Scratching my head how they got so many sissies on here crying about the little sharp edges. Weak. Like one of them had a little bit of sharpness that I sanded down with my fingertips This is pretty good for the money

### ⭐⭐⭐⭐ Gets the job done
*by S***M on July 25, 2020*

Nice value for a must-have tool. Kit gets the job done but is definitely pretty raw. Edges are sharp and metal is thin.

### ⭐⭐⭐⭐⭐ Tried 3 basses, 2 sizes. Both accurate on neck on tool itself.
*by K***F on May 22, 2024*

As you see in my photos I did a similar test as other guy that said these are off. These are so light it'd be easy to slightly skew the radius when pulling the tool up for this demonstration and prone to human error. As carefully as I could I traced top, then pulled straight up. It was flush! For the price these are great. They can feel a little sharp but nothing that will actually cut you. I used it to set strings on two basses and they sound great (tested tool accuracy on 3 though).
