As long as you are OK with a very loud squeak...

Makes a very annoying squeak when I use it that I can't correct even with WD-40

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

Makes the most annoying squeaking sound when you wind your strings

My only issue is the squeaking when turning the tuning pegs

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

It works as it should, efficiently turning the tuners on the guitar and helping making replacing strings a simple job

It works as it's supposed to

Works as it should.

Everything else works as it should, however.
