what i really like is that the padded material is very forgiving and holds the strings without any fret buzz and never damages my guitars.

But if it's not on hard enough, you risk string buzz

Quick, one handed technique to change frets and clamps very securely over the string with no fret buzz

After reading the other reviews I was concerned I might get fret buzz with this, but I've used it several times on both my Martin acoustic (16" radius) and Fender Strat (9.5" radius), and didn't get any buzzing strings with either

Personally, I hold it over the fret and squeeze slowly while strumming until there is no fret-buzz; this is in order to put miminal pressure on the strings

NO buzzing, looks amazing - I would say definitely worth the seemingly premium price
