Easy to install screen protect on S8+ phone. Dropped phone several times, but the glass is protected. Only drawback is when you're on the phone, the grease from my skin smeared the screen protector.
I recently purchased the Galaxy S8+, which is ALL GLASS (didn't know this at time of purchase). Have had at least two major "drops" and my phone is still intact. I'm sure I would have had to replace at least twice if I didn't have the Defender on.
I was hesitant on buying any screen protector. All the reviews I read didn't show many good reviews. Even the reviews for this were terrible. I figured since I had the Otter Box case, why not stay with the same manufacturer for the screen protector. I had no problems with the installation. I work in construction and haven't had any problems yet after two weeks on my phone. Down side is the price.
