Question: Is this made of a flexible material like TPU? ...or a hard material like plastic?
Document: Made of cheap shiny plastic, and once that thin is on your iPad it won't let go easy. Had a hard time with it.
This is a great cover for your iPad mini. This fits very well and is made to last.No fingerprints on the back and it will not yellow like some I have brought.This will fit perfect over the camera and will not block it from taking photos. Snap on and that's it. It will not protect it from hard drops but small bumps from putting it down to hard. Great product overall.
It works well with the Apple Smart Cover. But neither the Smart Cover or the clear back shield is going to offer you any protection for your device. I rated it five stars because it does allow you to see the Apple logo on the back and is very lightweight, yet pretty well made. It is slightly flexible, so it is easy to put on and remove if and when you want to. I recommend it.
It's plastic, and even though a hard-shell cover will break a fall easier -- and protect your iPad, the advantage of this one is that it isn't so heavy! If you want to hold your iPad Mini with comfort, this little cover will do the job! Great product.
Wanted to protect my iPad mini until I find a better looking case. :)This is a no frills functional simple 'flexible' hard plastic casing. Fits very snugly to the iPad Mini. Plus it comes with a screen protector - but beware the bubbles.Nice casing to have for those with a budget.
The hard plastic shell fits well and looks clean. The screen protector that came with it is impossible to apply without bubbles and has a sticky film that doesn't allow for a smooth swipe. The price is worth it for the shell but I would recommend buying a different screen protector.
I love my iPad mini and love how it looks. I wanted to protect it without taking away from its basic built in good looks.This is a minimalist approach, which is very practical. It is a clear, hard plastic shell that fits securely and snugly over the back of my iPad to protect it from scratches.
Again, Amazon sells great stuff at killer prices. Come on its a $1 worth of plastic. Why pay $40-$60 for a case or screen cover. You get a hard clear back case and a screen cover. Just add the apple magnetic (design and engineered from the mothership) cover and it's a winner.
This is the perfect solution to complement the smart cover. It fits easily and well onto the back of the Mini. The case does not intrude on the smart cover or Mini buttons. It also comes with a screen protector which I did not apply( read my earlier reviews on these items). The hard plastic protects the Mini and gives me peace of mind.
Good quality material - it's not at all flimsy or thin but it's still lightweight. Fits perfect. I like that it can be used with a keyboard cover or smart cover. Keep in mind this is not protection for dropping the ipad - it's just a cover to keep the backside clean and unscuffed. This came with a screen protector film, too,  which I haven't used yet (already had one on my ipad).
Answer: It's a hard material like plastic
