Easy to install; comes with everything to prep your screen. Fit perfectly. The only complaint was regarding the sliding camera Lense cover. It did not fit my laptop once the screen protector was on, so if you're purchasing because it comes with one, don't. Otherwise, a great product.

I reused this screen cover while changing laptop. The touch quality is awesome. It is just difficult to install, one needs to have experience by actually trying it on cheap screen guards.

This product was flimsier than I expected. I read the product as not just a blue light screen but also a screen protector but it seems likely given it’s construction it’s more of a filter than anything else. I’m not going to test it to find out.
