Harley Benton ConcertGuitar Machine Heads B3

no slips, even resistance of each peg when tuning. They look really good and feel solid.
update after a year: the D and A knobs are not ideal, you turn the knob but the string stays in place, so difficult to micro agjust. If you turn some more, and a little more again, then at one point the tone hops up, and you need to tune down a bit again. what i do is instead turning back i pulle the string up a few times with my fingers, and use this tension to go down for the perfect pitch.
I would probably try some other product next time
