These tuners seems well made, have a solid feel; not too tight, not too sloppy. The EZ lock feature seems logical but I probably won't use it as intended because I don't relish the idea of repeatedly jabbing the string under my fingernails while trying to unthread the tiny bit left after it breaks at the post. I use the locking wrap and I never have tuning stability issues. They look good too. They come with really nice beveled washers, five of which were black like the tuners and one of which was chrome. *BOOM* Three stars. I've been happier with a purchase...
