Review on 📱 BAZO 2-Pack Tempered Glass Screen Protector + Camera Lens Protector for Samsung Galaxy A21: Easy Installation, Anti-Scratch, Bubble-Free, Case Friendly, 9H Hardness, HD Clear by Hector Liamsi

It says it's a glass cover. It's not glass! It's just a high quality plastic cover. So that was misleading, but thankfully the plastic coating doesn't bother me. That works fine. It leaves some room for phone cases that fit snugly to the side of the screen. The guide frame is easy to use, but as I said, it doesn't come with any helpful instructions. This resulted in a website that went nowhere. Just slide the plastic cover over the top of the phone and then mount it in the frame and it fits perfectly. It took a lot of work to wipe the bubbles, but they came out fine. It was easy to apply the additional coating to the front camera lens. So it's good to have a little extra protection.
