### ⭐⭐⭐⭐⭐ Guitar tuners

### ⭐⭐⭐⭐ Ok value
*by V***N on 5 November 2025*

Overall good. One edge of fret rocker is off. Nothing unexpected.

### ⭐ Too Many Faults
*by A***R on 2 January 2026*

Some had mentions that the straight edge was not straight, that's about the only thing that was OK on my sample. First of all, the machining quality was very poor. Lots of sharp edges on the notches and the faces were nowhere near smooth enough. This would more than likely scratch the fingerboard of the guitar, especially those that have maple necks and are therefore varnished. However, that wasn't the main problem. The notches did not line up to more than the 7th fret making this an inaccurate and non-functional tool. The other metal item was no better machined. It's a shame really because for the want of a bit of extra care, this would have been a good purchase for the occasional user.
