I used it on my very first guitar, process was a breeze, although when winding it makes a irritating squeaky noise

making loud noise

Hate the squeaky noise it makes when turning the pegs

Literally the only downside is that it makes a TERRIBLE squeaking noise when you wind, seeing as it just plastic on plastic

And as bad as I play, anything that makes me look better is good.

The first time using it wouldn't cut the B string or high E string, very disappointing.

It runs the entire gambit of emotion where you are almost to that magical D flat (or likely E for some folks) only to have the string lose its tension and require even more tuning
