Harley Benton Parts Locking Tuners 6L Black

These are cheap locking tuners that's doing the work they're supposed to do. But there are some negatives if you're picky.

1) Their mechanics are uneven, you can feel that they're not smooth at all. Also the feeling are very different from one tuner to the other.
2) Metal feels cheap.
3) Screws don't fit into HB-guitar screw holes (the new screws are too slim), had to use my old silver ones.

Besides this, they're doing the work. They are locking down the strings which makes it a little bit faster and easier to restring a guitar.
