Review on Spigen Tempered Glass Screen Protector for MacBook Air 13 inch (M1/2018-2021) & MacBook Pro 13 inch (M1/2017-2021) [9H Hardness] by John Taylor

I use Spigen on all my devices and other reviews have been mostly positive so I decided to give it a try. Bad idea! First was the instructions for the phone, second I searched the internet for instructions and they only had instructions for mobile devices, no instructions for the computer. I think I'm pretty good at getting these types of objects onto my devices, so it's pretty simple: empty glass, clean, align, and smooth. The problem I have is that all the edges don't stay down or have bubbles and when you try to erase them they scratch the glass, even with a soft cloth. I may have received a defective one, but VERY disappointed in this product! The only reason it has 2 stars is because it offers protection. Given the price, I expected a lot more from a Spigen product.
