Nice case
Color: Navy/Green
Nice case for my 5-year old grandson. It is sturdy & was easy to put together. As a special needs child it works very well for him however, he does have trouble with the portrait view of the case. When using the portrait view, the unit often collapses as the prop doesn’t always stay in the locked position.

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!

Superb screen protector
Model: iPad 11th A16 2025/10th
Order this product with next day delivery for my new iPhone and I’ve had it on there for about a week. It was super easy to put the screen on the phone. It comes with like a guy that looks almost like a cover so excellent no air bubbles underneath knock on wood. I have not dropped my phone yet so I can’t speak to. It’s protectiveness but it seems like it’s gonna do a great job. I would definitely purchase again reasonable price good quality.
