Review on ESR Camera Lens Protector 2-Pack for Samsung Galaxy S21 Ultra - Scratch-Resistant Tempered Glass, Ultra-Thin (Black) by Cory Spence

Purchased as soon as I got my S21 UltraPros:1. Unmatched Adhesion - The adhesion level of this glass coating is STRONG. I had to take it off because the glass is basically losing to the new look (metal > glass) but it was the hardest for me to take off. I haven't seen such quality glue for a long time.2. Cutouts - 99.99% correct - after the holes in the lenses lined up perfectly, one side of the glass was like a streak off center. To be honest, you probably won't notice.3. The quality is strong, confident - the quality is definitely there, I broke my first one just to see how strong it is. it made me almost uncomfortable with how ribbed it is. Great job ESR.CONS1. Leveling the install - tedious for an OCS installer like me - the glass is so small (considering how big the camera cutout is) that not only can it be used as a large screen protector, I suggest masking tape (like gift wrapping) to use Use it as "tabs" to get a full idea of its orientation before you put it down (adhesion is no joke.) 2. The design is great, but so is. step back? - black "filler" fitting in the space where there is no camera only spoils the design. It's not their fault, but I recommend the fully transparent cover IF you like the metallic look Samsung has wrapped around the camera.
