Review on 3 Pack of Supershieldz Tempered Glass Screen Protectors for Garmin Edge 530 and Edge 830 - 0.33mm Thickness, Anti-Scratch, Bubble-Free Installation by James Cash

This is like the screen protector I use on my smartphone. The main thing is to install it in a dust-free environment. Rigid glass screen protectors are much easier to protect from bubbles than flexible film screens, which have always been a nightmare for me. I had a speck of dust and a small blister under me but not over the LCD area so they don't bother me. From time to time I've had hard protectors that rip but without damaging the main screen so I buy a pack of three or so which usually lasts for years.
