If you choose it, watch the video on YouTube: Mocolo UV Liquid Tempered Glass Samsung S10 Series Full Installation Tutorial. The installation is difficult but it can have very good results.
Pay attention to the sticker on the top part of the screen, cut it so that it covers exactly the speaker, otherwise when you remove it, it will create an air bubble (it does not affect the functionality).

At this price, it's a decent glass. Coming from Whitestone Dome and having paid 45 euros, the glass is fine. However, at this price, don't expect all the accessories that the Whitestone Dome had. The installation was easy for me, the application was perfect as it covers the selfie camera as well. If the adhesive leaves any gaps or bubbles BEFORE you put the UV light, you can gently touch it or even lift the glass slightly so that it falls back and covers the gaps, but all this with VERY gentle movements. Finally, the fingerprint works perfectly. Well, it loses one star because in selfies with flash, only light comes out... because it doesn't have a hole in the camera, the light gets blocked... bad...

After I applied it to the screen, I expected all the bubbles to disappear.. there was nothing and then I applied the UV to stabilize the liquid.. after a while, I noticed that the glass on the curvature of the screen started to detach.. I pressed it and applied the UV light again. In the end, it remained detached in two spots.
The phone also comes with a wallet protective case that closes. After a week of use with the protective case, I opened the phone and noticed that the glass had a crack without the phone falling.. which has gotten bigger. You get what you pay for.
Also, the fingerprint sensor works 3 out of 10 attempts.

At 1/3 of the price of the Whitestone Dome glass, I didn't expect much.
The package is very basic, missing the mold for the "flawless and proper" installation of the Whitestone and it doesn't even come with a cable for the ultraviolet lamp, only the basics.
The installation is the same as the Whitestone, meaning quite demanding, but if someone watches a few videos and has done it once or twice, they won't encounter any problems.
The result is the same as the Whitestone. Excellent fit, excellent clarity and feel. The same goes for fingerprint usage, meaning it's 10-15% worse than plastic film or the naked screen, but the protection is worth the sacrifice. I would give it a 4.5 rating because of this fingerprint issue if I could, but I'll give it to him for all the other advantages it has - plus the reasonable price.

Difficult installation, the glue dripped on both sides, there were 2-3 bubbles left. The imprint doesn't work well and it broke in the corner with the first fall. It's not worth its money, better to get a cheaper one and change it more regularly.

Quite durable and fits well on the screen, but personally, the fingerprint sensor no longer works well for me as I need at least 4-5 attempts and a lot of pressure to get it to work. I have also activated the touch sensitivity.

Update: Just when the fingerprint was starting to work better, my phone fell and took a strong hit on the edge of the table and another strong one on the floor.... I broke out in a cold sweat until I realized that only the glass had broken... the screen was fine.. very good protection !!!
