During installation, it did not adhere well to the screen, resulting in trapped air bubbles and I had to get another glass, the Whitestone Dome Tempered Glass which is the best. Inside, the displex does not contain a special installation kit, so it's a matter of how well you know how to apply the glass completely manually without any auxiliary accessories, which easily leads to making mistakes and getting air bubbles. Also, it does not have UV ultraviolet technology with glue, etc., it is just a simple glass. I would recommend a thousand times to spend the money on the Whitestone Dome Tempered Glass and choose that over the displex.
