This is my second set of Musiclily Pro locking tuners. Several other reviewers have mentioned the Asian factory these come from and, honestly, I don't care if they were made in Jethro's garage, as long as they work. These do. I will say that I was concerned when I first tested them. I always have a lot of project builds in the que, so I amass a lot of guitar parts. When I order a set of tuners, and they come in, I go through every one of them, looking for any issues which will tell me which build, if any, they would be most appropriate for. These tuners didn't have any wobble in any of the posts, which is a pretty common thing to find in tuners, although it usually doesn't affect anything, by the time strings are on it. What I did find, on the very first tuner, then on two others, was that there was some play in the tuner key. There was a significant amount of movement in the key, before it engaged the post. A little of that is enough to keep me from installing a tuner on a guitar, especially with a high ratio tuner. I was hoping the screw just needed to be tightened, which, luckily, was all it needed. If you ever adjusted these, you know you don't want to over tighten that screw, so I made some small adjustments at first, and those didn't fix the play in the key, but I finally tightened in a bit more than I normally would, and it seems to be okay now, and the other 2 required adjustment as well. I debated whether or not I should take off a star for that, but I think I'll leave it at 5, for now, if it's something as simple as that, and as long as the build quality at large seems to be high, which it does. My overall impression was that they are well made, but they probably aren't going over every tuner to make sure they're adjusted just right before it goes out the door, which, at this price, I think is acceptable. I will say that my other set of these did not have that play on any of them. But, if a small, easy adjustment is all that is needed to end up with a very good set of tuners, that's ok at this price point, and I will say that these are definitely a good value. After the quick adjustment, these work well, the ratio is good, the locking mechanism works well, no burrs at the post hole and the finish is very nice. I am really a fan of this nickel finish.
