Nice sturdy quality. Bright red if that's the look you're going forward. Easy to install great fit when they damp in the sound of your strap ever so slightly.

works very well and a very good price

If you don’t have a locking strap, these babies are a must have!!! Until you’ve had your strap fall off mid gig, you don’t know the terror of that occurring. You can avoid all of that with this product. Super easy to use. They come in a 4 pack so you can pop them on a couple guitars at a time. Built with sturdy rubber, I don’t think these blocks are falling apart, you’ll end up losing them before anything. Great design, they seem to fit on all guitars for the most part. They fit my acoustic, my bass and my guitars effortlessly and they’re not loose at all. Highly recommended!

Easy to lock in and looks like they belong. As described well packaged came earlier than stated. Would recommend both product and seller.

I buy, sell and trade guitars often. Mostly high end name brands. For years I have been installing permanent strap locks on all my guitars, which generally involves drilling a bigger hole for the locks and attaching the other ends to my straps. But when I sell the guitars it is difficult to put the original strap buttons back on because the holes are too large unless I fill the holes with glue and tooth picks and then re-drill the hole so I usually leave them installed and also include the strap section so the buyer has the whole set. Those are fairly expensive and not something that increases the resale value of the guitar, so I take a small loss on the strap locks. A few years ago I discovered these washer type strap locks and they have worked great since, with no modifications needed to my guitars. I no longer jump around like Chuck Berry or George Thorogood on stage, ( age related aches and pains from years of wild stage antics) so i don't worry that these strap locks would pop off. If I was more energetic I don't know if I would expect these to hold up, hence the 4 star rating, but for the past few years of using these, I never dropped a guitar or had one pop off. These are on all my guitars now.

Been playing guitar for 45 years, and never heard of these. Tim Lerch demonstrated a similar concept using the rubber washer from a bottle of Grolsh beer. These work great, are totally removable. Love them,

If you have trouble with your strap constantly falling off even just by the simple action of standing there, these are for you. They’re super cheap and extremely sturdy. If you’re looking to do cool tricks like a guitar flip I would recommend looking into a stronger one that’s made of metal, but these are a perfect use for just daily normal playing.

Works perfect
