Terrible. Don't stick properly to the screen. Tried all three. First two lifted off the watch when peeling off the front protector. Final one developed a large bubble I could not get rid off. A total waste of money, I threw them in the bin, rather than send back to Amazon. Anger over sense. Honestly, simply a waste of time.
Company contacted me via e-mail on reading the review. They agreed to send me a new pack of protectors free of charge. They arrived this weekend and I have now applied the first. Went on without problem and smooth, bubble free finish on the watch screen. Seems like my original purchase must have been from a faulty batch. Currently 4 star review, as no idea how hard wearing each protector is, but excellent customer service from this supplier.
