Was difficult to install but every screen protector is like that. With a large surface, I couldn't apply it without getting dust lodged underneath. You can pop a lot of bubbles with the tools included in the kit, but bubbles with some dust underneath will not come out. completely away. Luckily, they're barely noticeable when the monitor is on, but obsessive people may not be able to handle them. I bought it mainly for the anti-glare and it's not that great. It's better than no film, but I think I'd get much better glare reduction if I tried something different or at a higher price point.
