I also have theirs and it's it only one that fits my case. My only complaint is how the camera cutout is misaligned which seems to be for everyone who's used it.
While we're here and it's slightly O{n}T, Id like to thank the idiot anti-bezel patrol. No bezel recreated the same issue as curved screens, incompatibility.
With the tiny amount in the sides, the protector and cases need to share that tiny real estate. Now both fight each other for the edge. Boneheads.
Anyway, my experience has been good with them. Always liked their glass and they were the first competitors to Whitestone at a cheaper price AND extra glass. Excellent warranty, they actually have and honor it, customer service.
If I had one complaint it's that occasionally I get packaging dust or something which then becomes a pain.
All in all I love their stuff. According to Amazon they are a small business which makes supporting them that much better.
