OnePlus 7T Invisible Film Screen Protector

I reviewed my 1st Ultimate Shield tempered glass protector for my Oneplus 7T recently where I made a really poor job of fitting it. It got on my nerves having all kinds of dust stuck under the glass so I bought a 2nd one to replace it. In the meantime I had fitted other glass protectors from 2 other companies to a Samsung Galaxy S9 and a Oneplus 5T. The Ultimate Shield once again felt and looked much better quality, as I removed my old dirty glass it bent a fair bit but didn't break, unlike one of the others. The fit is excellent as is the black curved finish on the edges, it gives a real OEM look.
On reflection I don't think the installation procedure recommended is good enough, I learned my lesson from my 1st one and decided to use the sellotape method to form a hinge. This method should be virtually foolproof but there were 2 problems for me, the backing material is stuck fast to the glass so that the force needed to pull it off also dislodged the sellotape, the 2nd problem for me was that I wanted to use the "V" shaped notch at the top of the 7T to line up the glass but the sturdy tab used to remove the backing is located right in the top centre which meant that I couldn't really see the V. Still, after a while I lined it up and kept it dust free, the result now is superb. It feels great, is just as responsive as without the glass and looks outstanding.
I summary, for me there are some hurdles, but once cleared the result is a really superb tempered glass protector that looks exactly like it just came out of the factory.

Having used ultimate shield on my previous phone I wasn't surprised that it worked perfectly. However, the film peeled partially off just over a week into use and left lint under my screen even after cleaning to the best of my ability. This eventually happened on my last phone too but only after 3/4 years. Overall one of the best screen protectors I've used, if only they'd stick on a bit stronger.
