Review on 13.3 Inch MacBook Pro and MacBook Air Anti Glare and Blue Light Protector Screen (16:10) - Fits 2016 to Current Models, Including 2018 MacBook Air by Mark Sutovsky

So when I read the reviews and decided to buy I went through a few but decided on this one based on the good reviews and the ease of putting them on. I generally prefer to leave my privacy screen on my computer to protect the screen from bending and breaking and I haven't seen any obvious indications against it. Everyone said that with the privacy screen on, the computer would go to sleep. A few weeks after using it, I noticed a small crack on my monitor. I thought it was magnetized and after removing and examining it found it was cracked. The repair cost me $500 at the Apple Store. It's a pretty good product, but I'm sorry I didn't know it could hack my computer. I think the lever caused by taking a big chunk of magnet and a little pressure caused it to break. I've had my computer for over two years now and I haven't had a single scratch. This was indeed an anomaly as I am very careful with my belongings, you have been WARNED!
