I just received the product, so this is an initial review, mainly focused on delivery and ease of installation. The product was excellently packaged. It included all the necessary pieces, such as a cleaning cloth, liquid cloth, etc., and clear installation instructions. I didn't need to refer to the related video. The installation is extremely easy and simple. From the first check, after installing the protectors, I couldn't determine if there are any distortions in the received photos. I will return after using it for a reasonable period of time to comment on the durability of the protectors and any possible distortions in the photos in various environments (sun, clouds, night, night in the city, moving objects, etc.). Positives: excellent packaging, exceptional ease of installation. Negatives: none at the moment

I bought them separately to keep the set that came with the tempered glass screen protector, these seemed more "high-quality"! Indeed, upon receiving them, they appear slightly more high-quality than those in the set! They apply easily, and I don't see them affecting the cameras, etc. But honestly, I believe it is not necessary for someone to buy this kit if they get the ESR set that includes everything! Durability, etc. will be re-evaluated over time!
