Bought a set of the Grover tuning machines for the banjo ukulele I made from scratch (including hardwood frets). They work very well and are a very good value. Will be ordering more when I make some mahogany ukuleles.
I love these tuners. As geared tuners they're a great functional step up from the friction pegs. The knobs are nice and simple, very clean-looking. The mount flange is frillier than I'd like, but simpler than some. Good value for the price. -Adan
