I had a hard time applying it to my screen because of the size. I can say it may take 2 people to apply it. Good quality.

Be certain that device screen is COMPLETELY dust/lint free.
Item Package Quantity: 2, Item Package Quantity: 2
This comes in a two-pack, and both were certainly needed. After installing the screen protector the first time, I saw that there were several teeny/tiny specks of dust or lint that were visible and caused circles to form around the specks of dust/lint where the screen protector didn’t firmly attach to the iPad screen. It was not fixable. I learned from that experience. So, when I installed the second screen protector, I made sure there was no dust/lint on the iPad screen, and made sure that the sticky backing of the screen protector was also COMPLETELY free of dust/lint. Be sure to use the included “Perfect Screen Guard” to pick up the lint/dust before you finally place the screen protector on the device screen!! I give this a “5” because it did great after being certain that there was no dust/lint.

Good screen protector but
Item Package Quantity: 2, Item Package Quantity: 2
I had to buy two of these screen protectors you have to really make sure there’s no specs of anything on the screen before applying or it will not stick anymore but maybe that’s my fault haha, the second time around it was put on correctly and I haven’t had any problems so far
