Flipkart SmartBuy Edge To Edge Tempered Glass for Mi K20, Mi K20 Pro  (Pack of 1)

Well first of all its a rebranded product, it is made by another company and sold by flipkart as a smartbuy product. This screen guard is not fully cut to cut or no other screenguard will be because of 2.5d curve glass. this covers some 1-1.5 mm screen area from every side of your screen with black film.
the good thing is it has glue all over area so it sticks fully on screen. It has olephobic coating so no finger smudges and has a smooth gliding. overall a good product at this price.

Usually these black bordered tempered glasses are smaller than screen. But this one's way smaller. The quality of tempered glass and glue is very good. No bubbles while putting this even after removing and putting it again. But the borders are very thick and invade display.

This is my opinion. This glass has black edges which covers some portion of the screen all around. The bezel looks much thicker and ugly. I would suggest you go for an all transparent glass. PUBG players will notice the difference as it will cover half of the ping ms on the bottom as well as half of the number of kills and players remaining on the top which you will find very annoying. But if your're okay with that then go for it. It fits perfectly btw with no bubbles whatsoever.
