### ⭐⭐⭐⭐⭐ Quality, solid product to help keep your guitar strap attached.

Good value for money, fits on Gibson and Fender guitars, its a quality rubber, is versatile and can be stretched, easy to use, remember to put on top of the strap, sometimes they can come off when playing, if your strap locks are too small.

### ⭐⭐⭐⭐⭐ Actually does the job.
*by B***T on 30 April 2024*

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.
