I recently ordered an Occushield for my monitor. Unfortunately, having measured my screen width (rather than taking a horizontal measurement) I received the wrong size! Mickey, in customer services, was extremely helpful in ensuring the right size was despatched, and at no extra cost to myself. I'm typing this review through my Occushield replacement and, I'm pleased to say, it's very easy on the eyes. I've also received I-phone shields for other family members...great Christmas presents :) I intend to order one or two more because what's better than giving something that cares for eye health.
