As someone who has a severe problem with my eyes it’s essential that I do what I can to protect them this is why I chose Ocushield. It’s really difficult to quantify the benefits but I guess it’s just ‘peace of mind’ on my behalf to do my best. After a couple of months of having it on my phone the left hand corner started to de attach itself …… I contacted the brilliant customer services and they sent a replacement…… alas the same thing is happening so I can only presume my screen is somehow not perfectly aligned. I was super happy with the treatment I received from Ocushield but I think the issue is with my IPhone XR not Ocushield. Nowt I can do about that but I’m completely trusting of Ocushield and thoroughly recommend the product.
