So I bought these because being Dunlop, I trust the brand. I don't even mind that they are sorta big and bulky. The only problem I have is, they scare the piss out of me. Its not a "tighten washer and nut" situation with what ive normally seen on strap locks. These have pegs that insert. Its so hard for me to trust these, I always have 1 hand gripped firmly on guitar even if just adjusting the amp I clench my guitar. So scared that the little metal balls things will just slip, peg fall out and ruin a $500 guitar. I havnet had a single problem with this system yet, and I never hope that I do. But if it happens there will be an update to this. Good product so far, just wouldn't recommend it. There is too much crap in the world to be worried about, strap locks shouldnt be one of those things.
