Solid case.
Color: Sky-Blue
Love this case. Fits great and the color is great! The keyboard is nice and it even has a little spot for a stylist.

Cheap and good
Color: Black, Color: Black
I chose the color black and it gives a really nice look, especially with the multicolor led lights around the keys. It is very easy to clean and you can shut off the keyboard to prevent any mess with the iPad. The magnet is very nice and keeps the keyboard in place. The keyboard doesn’t easily slip or anything so it holds the iPad very well. Only bad thing is that over time the iPad begins to scrape off the pain and it leaves your keyboard with some white spots all over :/ but if looks isn’t something that you care about, this is the keyboard for you. Don’t use it for gaming because there is a delay in functionality when you press a key and then try to use the pad. Also, you have to press the keys a bit harder than the usual keyboard. But for the price? This is a great item! Definitely worth my money

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.
