Have had a set of these on one of my guitars for 10 years now with no issues. It makes strapping up a very quick process. So good in fact that I decided to put them on two more of my guitars that I use to play out with. The Dunlop Straplok system makes the process of switching out a  guitar on stage a very effortless move. It also affords a quick breakdown when removing the strap before packing the guitar in its case. Great quality. Be sure to match the finish to the machines on your guitars for a professional look!
