I’ve noticed that I’ve been able to fall asleep very quickly since getting Ocushield - so it’s resolved that part of insomnia for me - for this alone I give it five stars (I still have recurrent night time waking insomnia which is probably triggered by something else). My only negative is the price - I’m on my second Ocushield in a year and when installing it I got some bubbles/dust in there somehow (first install was perfect). This meant I had to lift the screen off a bit and adjust. I will say though that the tiny bubbles do seem to go away over time. But the area where I had to lift it at the edge still has a mark that shows it’s not fully stuck back down… guess I’m now just looking forward to when this one gets scratched up enough so I can have the pleasure of dropping £££ for a fresh one. I will say tho that they are quite sturdy shields and don’t smash too often compared to others. Seems they can withstand more impact than usual glass protectors. Highly recommend if it seems unaffordable and you have crippling difficulty falling asleep at night - it’s worth giving this a try to see if it helps.
