Yeah, I've been using it forever... It works great...

BTW, I play almost exclusively slide guitar and I hate the sound of new strings, especially on my resonators so I get up to a year on one set of strings and Fast Fret allows them to continue to be very playable...

Back when I got my first Fast Fret it came in a metal can like old time 35 mm film but the new Fast Fret comes in a plastic conatiner... Not as cool but still the same good stuff...

Buy it... It works...
