10/10 protector, managed to apply perfectly on the first try. No need to remove any dust from underneath. Blends in perfectly and protects the Switch from the silly dock issue.
Yes, I took some precautions before applying and you need them if you want the perfect fit but that's just the way physics and nature works. So go take your Switch and the protector to the bathroom, take a warm shower so dust particles aren't flying everywhere (moisture wins with dust) and just follow one of the guides on Orzly youtube channel to apply (use the dust stickers to hold the glass in place instead of using them on the screen) to install it. Managed to get it perfectly aligned and without any bubbles/dust underneath the glass on my first try.
As a bonus it comes in pairs so you'll have a spare piece of glass just in case
