Worth it!

Great buy! Worth the money and the color is nice. The keyboard works, some buttons I haven’t figured out but for the most part it’s worth the purchase!

Great quality and functional
Model: iPad 11th A16 2025/10th, Model: iPad 11th A16 2025/10th
Fantastic screen protector! Adheres flawlessly and is easy to install. Doesn’t interfere with screen functionality and doesn’t go cloudy or hazy with use. It fits perfectly on my iPad 11 and was an absolute bargain compared to other protectors that cost 3x as much and never stayed in place without bubbling. Color is crystal clear, you can’t tell it’s there and it is easy to clean too! I definitely recommend!
