Review: Actually does the job. - These give an additional level of confidence to what can only be described as the terrible strap attachment found on most guitars - designed to fail eventually. These aren't in the same league as the dedicated quick release devices such as Schaller strap locks, but if you are keeping the strap on the same guitar then they will help to keep the stap in place. Depending on the strap thickness and guitar mount these can be easy to fit or not! Found on one guitar had to unscrew the mount slightly, fit the flex lock strap and then tighten it up again. Well worth having if not using a quick release type device, plus here is no hole drilling etc. Would I buy again - Yes.
Review: Perfect - I've been meaning to get some strap locks for a while and when I saw these, with the little tabs on the side, I thought they'd work for me as I might need to change the strap. And they are. They work perfectly, go on well and come off easily- but not until you take them off. No more having to bend down at the speed of light to catch my guitar before it take the floor out.
