I have had these on one of my guitars for over a decade.
Best locking tuners I have ever had, small, neat and precise.
The make is perfect as I have always experienced with all things Hipshot, and installing them is a piece of cake, however because of the different position of the anchoring screw, you do have to make sure they are straight before you drill the new holes.
Extra plus, they are sold separately so you have no problems in terms of which set to order, you just get as many left and right sided as you need and done, love it.
Honestly, the only product on pair with these Hipshots are the Planet Waves Auto-Trim tuners, but with the Planet waves you do have the issue of being limited by the available sets (6 standard in line or 3x3), and that's a problem since most of my guitars have 4x2 or 3x4.
All in all, you need high end tuners, do yourself a favor and get these Hipshots.
