Great quality product
Size: iPad A16 11th/10th
This is a great quality product that is easy to apply. It's scratch proof with no glare on the screen. We were able to apply this screen protector with no bubbles on the screen. It's heavy duty and will prevent screen cracking if this is dropped. I would definately recommend this product!

Screen protector
Size: iPad Air 11" M4/ M3/M2, Size: iPad Air 11" M4/ M3/M2
I’m really happy with this screen protector for my iPad. The quality feels really good, and it fits perfectly on the screen without affecting the display quality or touch sensitivity. I was worried it might make the screen look dull or reduce responsiveness with the Apple Pencil, but everything still works super smoothly. It also helps reduce fingerprints and keeps my screen protected from scratches, which gives me peace of mind while carrying it around daily.

Good protection, but some bubbles remain
Size: iPad pro 13'' 7th (2024), Size: iPad pro 13'' 7th (2024)
This screen protector does a great job protecting my iPad. It feels solid and the screen still looks clear and responsive after installation. Overall, it gives good peace of mind for daily use. Installation was simple and straightforward, which I really liked. It didn’t take much time and everything you need is included. The only downside is that there is always a small air bubble that stays under the screen at a certain angle and doesn’t fully go away. It’s not a big issue, but worth mentioning. I’ll attach photos after installation so you can see how it looks. Overall, a good product with minor imperfections.
