Great product.
Very effective, quick and easy to fit. Works well with standard strap buttons but not the combined output jack/strap buttons fitted to many acoustic guitars.

A nice tight fit that keeps the straps securely in place
These are basic but do the job intended very well. They keep the guitar strap safely attached to the guitar and are a very snug fit so they won’t work their way loose. So far they haven’t stretched or come away from the guitar body. Can recommend

Not suitable for Squier Mini Bass, but ok for any guitar with normal sized strap pegs.
Have used these for numerous guitars and not had issues. My daughter has an Ibanez Mikro and the secure the strap perfectly…however, my son has a Squier mini bass and they are not suitable. The strap pegs are smaller than most used on other guitars and basses, so they just fall off and done secure the strap.Any other guitar with normal pegs though, absolutely brilliant, not issues at all, would recommend.

Excellent product
In my opinion the best of this kind of product because they have the tab to help pull them off. I used to use strap locks, but in all honesty these are just as good for a fraction of the price and you don’t have to change your strap buttons. Better than the rubber top off a Grolsch bottle because they’re black and have the aforementioned pull tab. Can’t go wrong!

A great way to protect your valuable instrument.
A simple yet effective solution to my many near misses with my guitar strap slipping off. Wish I’d discovered them years ago. Low cost but high impact 😁.

Strap attachment security
Cheap and cheerful way of adding some security to guitar strap attachments

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.
