Purchased to protect Nintendo Switch from 6 year old boy. You only need to buy one pack as each pack contains 2. I have been using Maxboost iPhone screen protectors for many years and when I saw one for the Switch it was the right one. The installation is very easy. Take your time. Read the instructions. The presence of dust under the screen is not a product defect. wash your hands Install in a clean, dust-free environment. Thoroughly clean the switch with the cloths provided. After you've done all this, place it on the table for close inspection. If you see dust particles, carefully remove them with tape. Put the glass on the switch and squeeze out the bubbles. Once activated, that's it. It looks like glass because it is glass. Super thin and you don't even realize it's there. Our Switch has been dropped many times while gaming on hardwood floors and hasn't got a single scratch. Great product for switch and insurance if you have kids.
