Great case - does its job!
Color: Black, Size: Case for iPad (A16) 11th/10th Generation 11/10.9''
This is a great case for a kid (or adult) who is rough on their iPad. My kids iPad has been dropped, thrown, etc. and the case has done its job. We like having the built in screen protector which is fairly easy to clean. The case has a strap and a kickstand if needed and looks professional if that’s important to you. Worth the money!

Great Case, Just Minor Issues
Color: Black, Size: Case for iPad (A16) 11th/10th Generation 11/10.9''
This case is an overall good case, in the sense that it does a good job protecting the tablet. It covers the entire screen with a plastic screen, which I personally like and don’t mind. It also had a kick stand and sting to hang it, which is a must for kids. My kid has not broken his tablet since getting this case, BUT he did not last very long with it on. The plastic screen protector and the front piece, made it super difficult for him to pull down his control center from the top right corner. This annoyed him so much that he ended up taking the whole case off and eventually losing it.
If they could make the plastic sheet more fitted to the screen so that the issue is fixed I would give 5 stars.

Great value to protect your ipad.
Color: Black, Size: Case for iPad (A16) 11th/10th Generation 11/10.9''
Nicely made and thought out product. Fits perfectly and comes with everything you need. Easy to install, looks very sturdy. The shoulder strap it comes with to carry it around makes it even more versatile.

I use my iPad for work!! This case is a fantastic addition - easy to use when I’m on the couch or in the Office. Stand is easily changed from vertical to horizontal - Velcro handle can change large or small. My stylus also attached to the back so everything is ready on the GO
