For anyone interested in the Whitestone Dome glass:
I just received mine today, and I am extremely happy about my choice (so far). It was slightly complicated to install (as the video would suggest), but following the video resulted in a pretty much perfect installation for me. There was a tiny bit of excess adhesive at the top of the protector by the speaker bar, but a few scrapes from my finger nail took care of that.
Case compatibility:
I have the Spigen Neo Hybrid, as well as the Olixar X-Duo (using the Olixar and I actually like it a lot better than the Spigen). I specifically asked Whitestone's Amazon front if the Neo Hybrid was compatible, assuming that if the one is the Olixar will be as well (same basic construction). They assured me that it would be, but you need to wait 3 hours post-UV for the adhesive to fully cure before putting on the case. I did that, put the Olixar on, and lo-and-behold, it fits perfectly. I don't have any uplift whatsoever. I haven't tried it with the Neo Hybrid, as the Olixar is my daily driver, but I can only assume it works.
Impressions:
Not the sleekest of protectors out there. The edges of the glass are raised, not beveled down like a true 2.5D protector, however I barely notice with the case on. However, it's the first (and only, as far as I know) screen protector that actually works full-coverage on the S8. Because the adhesive is full-coverage, there's no air gaps and no loss of sensitivity. The force-touch home button works like there's nothing there but the phone itself. My only concern is that the glass is thick enough that if placed face-down, the lip from the case may not be enough to prevent the screen from touching whatever surface you're laying it on. That being said, since it's a tempered glass, it should be fine scratch-wise (apart from sand/granitic dust, which would still scratch it regardless of the protector) and will protect the phone screen from shattering. I'll be leaving it on, so I don't have any indication of how easy it is to take off. But overall, if you're clumsy like me and need something a little extra there to prevent your screen from cracking, I'd highly recommend the Whitestone.
