Rubatone Locking Guitar String Tuning Pegs Sealed Machine Heads Tuners Tuning Keys 6 In Line for Right Handed Electric Guitar or Acoustic Guitar Black.

I put these on a partscaster I built. They seem to work fine. As others have mentioned the enclosed screws are a size to small. I used the ones off of the original tuners which are a size larger. Great value for the money. Would I put them on a high end guitar? Probably not but for my needs they work great.

Honestly expected worse for the price. Great all around product.

These tuners dropped into an older Ibanez without the slightest issue. I had the original tuners out already, so in under 5 minutes these were in and ready for stringing. The tuning adjustment so far is smooth and with better incremental precision than the original tuners. So they accomplish the intended result.My only gripe, and loss of one star is the packaging; the tuners were dumped loosely into a plastic bag together, with the locking pegs turned out, no individual protection, and that did mar the finish on some of the the tuners. For the price, I suppose it’s to be expected, but I’ve bought other locking tuners that were only a few $ more that were very well packaged. Even just a very simple box with slots to separate the tuners or a tiny bit of foam around them would have been welcome.

All parts neede were in the order - this was one of the easiest set of tuners to do an upgrade with on my Devlin electric guitar. Assembly on the headstock was a breeze plus no issues with the locks using a set of D'addario 9's. No slippage on tuning - buy 'e cuz you are gonna love 'em!

Very Happy with this purchase. They work great and hold tune even after heavy hard playing and whammy bar action. Makes restringing a breeze.

I absolutely love these !! I bought alot of budget tuner these work better then any I have bought. They hold tune and locking system is great! I will be buy more.

These are remarkably nice. Work well.

Not quite ,5 star quality BUT, good quality for the price!
