I've had and used Rhino shield on two previous devices over the past 4 years, both times being simple and easy to install. However, this time round the instructions and video show one product but the supplied goods do not fit the same. The guard layer has 2 protective layers on each side, not 2 and 1 as the instructions show. Whilst attempting to fit the guard onto the screen, I realised that although I had removed films 1 & 2 from the guard and that film 3 should be on the shield still, it in fact had a fourth layer on the side of side 1 which was still on the shield. So as I removed layer 3 and continued to press down onto the product to get any air bubbles out, all I found was the guard was not adhering to the screen properly. I think this layer is meant to peel off with layer 1, but being made of a different material and being stuck more so to the guard than the film it peel off. Due to this, I had to fit the guard to the screen with no tabs or anti lint layer on the guard. The screen is covered in air bubbles from dirt/lint getting onto the guard whilst faffing around with the layers. ALSO, the pull tabs designed onto the rhino guard to ease installation are permanently apart of the shield. I had to cut them off from both top and bottom to dispose of them. This is after the guard has gone on though, so you have to repeat the process of pushing air bubbles out afterwards. I am genuinely sorry to say I won't be purchasing Rhino Shield again, which is a shame as I know from first hand experience how good there product is at protecting your screen. Attempted to fit to Galaxy S10e.
