I recently bought the Opentech tempered glass for my mobile, and I’m very happy with the quality. The glass fits perfectly and maintains the original screen clarity and touch sensitivity. It’s smooth to use and provides great protection against scratches and drops. The installation was easy with no bubbles, and the packaging was neat and secure. Overall, a great product from Opentech — definitely worth the price and highly recommended!

OpenTech Tempered Glass is AMAZING!!! Worth buying for S24 Ultra - Ultrasonic fingerprint supported(the best thing) - Super sturdy - Easy installation - Size is very good - Fits perfectly on the screen - Privacy protected - Easy to clean - Absolutely affordable Functionally the best quality at this price.

Product is good nice packing comes with instructions Ultrasonic Fingerprint Support. Rouxh is good and smooth. Privacy is not that great.

Good privacy protection. But not that tough what's claimed, it got cracked easily due to keys. Mine got cracked in 15 days of use that to over finger print scanner area.. can't use the figure print scanner now. Alos when we use it first time I need to reset the finger print scanner.

This is my second purchase of this product. I use a Redmi Note 10 Pro Max. The first time I bought this screen protector around 7 months ago, I was unsure as I have never used tempered glass earlier. I decided to ditch polymer covers entirely and take a chance with OpenTech. After using this, I am convinced that this product and package is created with a lot of care, and it has truly earned its 5 star rating. I had read some apprehensions from older reviews earlier regarding the edges not sticking, air bubbles forming etc - and all I can say is that my two covers have behaved perfectly, but we need to closely follow the instructions and keep our hands and the environment very clean and dust-free. Yes, my OCD friends - you know what level of clean I am talking about. I am a doctor by profession, so I have a clear concept of clean oil-free hands (and what are the common mistakes that majority of people do). Proper handling of this product is essential to enjoy perfect adhesion. (I don't have any special soaps at home by the way, I just scrub better!) I was impressed with the stickers and ready swabs supplied along with the screen protector - these are adequate and do the job well. I also found myself wanting to reposition the glass a few times since the first application was not perfect - and the product definitely allows us this leeway. That being said, there are guide stickers in the package that should make the positioning job easier and more precise - I thought that is a nice touch. I get annoyed even with a single strand of dust flying while I work - so the dust removing sticker came in really handy during my work. It must have taken me 10 to 12 minutes to complete the installation, and I am a complete beginner at it. The only doubt I have - where other users can chip in - is regarding using this screen protector along with the original OEM back cover / phone sleeve. I use a third party back cover which covers the camera panel and has a slightly smaller lip; so both these products work well together. I think for this protector to work with the original sleeve, it would require a very high precision of placement, and high skill level; maybe we can put the sleeve first and then stick the screen protector on. It's not impossible but it needs that extra effort. Once you put the sleeve, if you find the protector slowly peeling from one of the corners - you know you need to repeat the effort. Try again, it's possible to get it right. The protector has a black ring around the camera hole - I searched very hard for something that does not have the black ring, but now in real world use I find that the ring does not bother me. Over the 7 months of using my first screen protector, I was surprised at how scratch-free it remained. I am generally a careful user and tend to wipe the surface multiple times every day - but the coating stayed almost like original throughout the period. In fact I feel the appearance and touch sensitivity is almost as good as the original glass even a few months down the line. For picky users, be informed that there may be an occasional time that the phone stops registering our touch while swiping - although I suspect the issue may be more with my phone than the protector itself. Optical clarity has remained good over time and I expect this to be the case easily for an entire year or even longer. Text and images remain crisp and sharp, colours are true, and after a while you forget that you have a screen protector on. One word of caution for those that use a lot of hand sanitizer - make sure you do not accidentally drop any sanitizer onto the phone. Also try not to handle the phone while hands are still wet with sanitizer liquid. I have never done it, but I suspect that any sanitizer that gets in between the screen and the protector will affect the adhesion to a great extent. Just be careful. All in all, I highly recommend this product! For those on the fence between polymer vs tempered glass, I suggest you give this one a go - this product and package has a lot of pluses going for it. Make sure you match your phone model correctly.
