I don't usually write about negative things, but since this is a fairly reliable accessory, I have to. During the first test, the lock, tightened to the maximum, gave out on both sides of the strap one after another, the first one was especially painful, as the guitar hit the floor headfirst, I'm currently just trying to see if I escaped with a broken pickup switch. Everyone should buy a Loxx brand lock, it's not more expensive, but I've had no problems with it over the years.
