Apple Watch Screen Protector 40mm, [2 - Pack] Tempered Glass Screen Protector, Anti-Scratch Resistant Full Coverage Scratch-Proof Screen Film Compatible Watch 40mm Series 4

Yeah, this stayed on just about 20 minutes. It's the right size, but the edges are not flush and easily snagged on anything. Anything at all. That would have been fine with enough glue, but there's only a *very* thin line of the glue along each straight edge. I was thinking this would be somewhat like the tempered glass protector I have on my phone, that has rounded edges and adhesive over the whole surface. If there was more glue on the watch protector it may have stayed even with the snag-prone edges, who knows? As it is, it would stay on fine if you weren't wearing your watch, but then why would you need a protector? Bottom line: nice glass, WAY too little glue.

I recently purchased this protector for my watch. It was very easy to place, although the guide tabs were not in the box. It fits so well if you didn’t know I had it, you couldn’t tell it was even there. The touch screen was not affected by it at all.

You will waste your money because it will not work. It might look good for maybe 1 hour max then fall of your watch. Customer service is a joke.

This was not worth the small price tag. I gambled and failed. I would avoid this.
