Good for the price. You can better but you will pay a lot more.In my case it was for improving Chinese import guitars that always have very poor machine heads. These are perfectly suited for a budget guitar.They hold tune well, zero wobble in the mast, and have good fidelity.The only downsides are one of them had very slight scratches if you look closely, and their was a slight crunch turning them the first time. Very minor stuff for what is a budget item. Recommended.I have no complaints for the mkney
