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.
