Good protector but bubbles at install
Model: iPad 11th A16 2025/10th
This is probably the 10th or so glass screen protector I have bought and installed for reference. Compared to others I’ve used in the past, it was just as easy to install but I struggled with bubbles under the screen and I took weeks for them to come out. Works as it should, good visibility and protection, just went it was easier and quicker to install.

Apple is number one
Style: Wi-Fi, Size: 128GB, Color: Blue, Configuration: Without AppleCare+
The best iPad it’s worth the money it works perfectly fine I think the battery life is fine, but it probably needs a little bit of work, I would choose Apple anytime of the week. The durability is perfect and everything and the gameplay is absolute amazing. this is also for personal use and probably college use. I’m probably going to use this for college as well.
