I have bought the expensive OEM tempered glass. It was a nightmare. This Supershieldz product went on very easily. A few very small bubbles near the edge moved easily. Highly recommend and will buy again. The black border is great. I was shocked that I put it on and was done so quickly.
Supershieldz by far has the best screen protectors. I've tried 2 others on OnePlus 6 T and both were nothing but aggravation. The Supershieldz went on the first time and what few bubbles there were they were easy to remove. I did have two small bubbles on the bottom but with in two hours they were gone. The fingerprint sensor worked without issue. I highly recommend this product. Great company, great product, and fast shipping.
