FRETLORD FretLightZ Guitar Fret board LED - Blue

Honestly, I have zero idea what people are talking about when they say this works....IT'S A TRINCKETT...paying $9.99 and over $4 for shipping was truly OFFENSIVE, and I have never said that about anything I've ordered from Amazon. The thing didn't even attach to the neck of my bass guitar because of the design. It's a complete joke, and not in a good way. I'm super disappointed because when I play in a dark room I need to see the neck and I'm tired of trying to shine my music stand light on my bass...you live and you learn! D in New Orleans
