Review: Great product. - Simple and effective
Review: A simple little must have item - These are cheap insurance to make sure your strap does not pop off. I recommend these with the little tab on them. It makes them way easier to install or remove. They fit perfectly on a Stratocaster and I have no fear that they will pop off. I don't think I'd go flinging the guitar over my shoulder but in normal use they are more than acceptable. Guitars are expensive. These are cheap. They seem durable but I leave them on. They would probably stretch out if you installed and removed them on a daily basis but I see no good reason to do that.
