I bought it because of string buzz on my guitar. i used larger gauges (12-52) for my A tuning, so i always struggled with fret buzzing and can't 100% eliminate it, and this thing works great. With it i have no buzz and recording guitars it's much easy, because notes stay in tune and being heard clean. Looks great, in comparison with normal hair gums i used before. One little detail - i have to put it off when putting guitar in case, cause it takes some space and in my case i can't close gigbag whit it on. On other side material the Fretwrap made of is very soft so don't be afraid of scratching wood on freatboard, polish on the neck or something like that. Looks great by the way.
