Exchanged together with a nut on my LP kit and it does hold the tuning better. Nice budget alternative and if I'm not mistaken several colors possible.
Good upgrade for the kits. Make sure to check thoroughly if they will fit, otherwise you will have to drill in the new screws and hope the tuner covers the old screw holes.
For all of those wondering, its perfectly fits the Harley Benton Single Cut guitar kit and also, as far as I checked, the gold ones too.
