I purchased these Grover Ukulele tuners because my Baton Rough Uke would not hold tune, I have Grover tuners on my guitars and I know that they make quality products. They are amazing quality, well built, and look fantastic. To fit these it was very simple, even somebody with no skills would be able to install these using a screw driver. The tuners totally transformed my Ukulele, these have a 16:1 Ratio, and NEVER lose tune, before my Ukulele was an average instrument, now I love it. These are very cheap for what you get, if you want an upgrade for your ukulele I would highly recommend these. Grover make the finest tuners in the world.
Usual Grover quality - much better than those supplied on most mass produced ukuleles. 16:1 ratio makes it easy to make fine adjustments. These geared tuners stay in tune much longer than traditional Ukulele pegs. Slightly longer Rollers on these is great if you are making your own Uke and are putting a veneer on the head stock.
