Musiclily Pro 3R3L 15:1 Ratio Full Sealed Locking Machine Heads Tuners Tuning Pegs Keys with Big Hex Button 45 Degree Screw for Acoustic Electric Guitar

These are a great alternative to more expensive locking tuners. They are very responsive and I definitely see an improvement in tuning stability. I easily installed them on my Donner DMT 100 and they were a very inxpensive upgrade which made a great difference. I will bebbuying more of these in the future.

The tuners are fine, but the screws were terrible. One was broken on arrival, one sheared off in a pre-drilled hole (with normal pressure from a hand-held screwdriver) and two more stripped with normal pressure applied.

I bought these to replace tuning pegs from a different manufacturer that did not operate smoothly. Here’s some pros and cons:On the pro side, silky movement and easy to turn and locking mechanism works well.On the con side, some tolerances were a little tight, but not enough to inhibit installation.Overall nice tuners at a decent price, I would recommend.

Perfect stock-looking replacements that lock. My set, although new, looked somewhat aged but my guitar is almost 20 years old so it all matched. Good twist resistance & stays in tune

Wasn't too sure bottom but so far they work really good
