Here is my 2bit review:
After starting to see scratches on my S8, I started researching and found this thread and looking at Whitestone Dome Glass, decided to buy it.
First screen arrived on March 25, 2018.
I followed the instructions like others here have and noticed that it was starting to peel up on the power button side with the Spigen Neo Hybrid case installed after a few days of use.
Used the second tube to try reattach it again and this time it took hold without any issues.
Then I dropped the phone.... on a geode... while trying out the new photo light box.... Thankfully, it landed on the tempered glass protector and did it's job marvelously.
I was able to get a replacement sent via warranty on July 19, 2018. I paid $10 USD for the warranty replacement kit, which came with everything.
This was the revised version since the install kit parts looks different from the original.
Installed just as good as the second time though and also bought one for GF's iPhone 8 (HHHIIIIISSSSSSS!!!!!)
Since then, I'm still rocking the replacement on the original tub for that and am about to pay for the replacement kit for GF's since she dropped hers and the glass again did it's job of saving the devices glass.
With all that said, I will agree that you can see where the protector is on the device, but I've gotten used to it and am glad it's done the job I've needed it for.
