The glasses and iPhone screen are fantastic - crystal clear. The view is slightly yellowed but still crisp and perfectly clear. The MacBook screen however seems to be use a different technology: the view is not yellowed at all but it is really unfortunately just a little fuzzy/blurry which is disappointing. Peeling it back reveals my comparatively super clear screen underneath. Its manageable but really not ideal. Also the installation instructions were the wrong way round. I applied it following the video and pack instructions exactly but ended up with air bubbles stuck underneath and the matt and shiny sides the wrong way round, so had to reverse it and do the opposite of what the instructions said to get it the right way round, where it is still blurry. Customer service experience was ok however and I was part refunded. I will continue my search for a laptop screen that doesn't blur the view and use this until then.
