It is a very good screen protector for the money! It may not be so durable over time, but definitely the quality-price ratio is very good!

It was purchased a month ago for the Redmi Note 11 Pro, not the Pro+ which, however, have exactly the same screen dimensions, 6.67 inches (source: https://www.gsmarena.com/compare.php3?&idPhone2=11180&idPhone1=11333). It protects quite well initially and adequately covers the screen without creating any problems with the Spigen case I have.

I deduct one star for two reasons:
1) I was in the bathroom and it fell for the first time from half a meter and cracked immediately. The case fully protected it, but the impact from the corner combined with the weight of the phone greatly damages this specific glass. Compared to Spigen tempered glass, the difference is night and day, really.
2) It covers 1mm on the right and left side of the screen. Not noticeable in everyday use, but only when watching videos on YouTube and gaming (e.g. Clash of Clans). I have been using tempered glasses on the phones I have changed for years, both mine and my friends', and I installed this one without any problems at all. If it didn't have the black border (which I have no idea why they added...), this issue wouldn't exist.

Do I recommend buying it? No, unless you can't find the corresponding Spigen glass for your phone.
Update 2/12/2023: By chance and after some searching, I realized that the Xiaomi Redmi Note 10 Pro has the exact same screen as the 11 Pro, so I paired it with a Spigen glass for another phone: https://www.skroutz.gr/s/28292911/Spigen-Full-Face-Tempered-Glass-Redmi-Note-10-Pro.html
