SURVIVED FLYING OFF A MOVING VEHICLE! BEST CASE EVER!
Color: Sakura Pink, Color: Sakura Pink
I don't leave many reviews, so the fact that I am even making an effort to leave one for this case should be testament enough on how impressed I've been with it.
First off, the tl;dr: 5 STARS HOLY COW THIS HAS EXCEEDED MY EXPECTATIONS.
I bought this case for my clumsy 5 year old daughter. I thought she'd really like that it was pink and I liked that it had a handle that she could hold onto. I hoped that the spongy padding on the case would protect it from the hundreds of drops that it would inevitably have, but it was a cheap case. I could only be mad at myself if it broke. She really liked it, though. I did too. It was easy to install and fit perfectly. It gave great protection to her ipad, lets her prop it up on the table easily, and she can carry it from the handle. So I'd have given it 5 stars just based on all of those things along.
What I did not expect was for me to accidentally sit the ipad on top of the car, forget it was there, and have my wife drive the car to the grocery store with it on top. It fell off less than a mile from our house and laid in the middle of the road in the light rain for a short amount of time before a good samaritan stopped and snagged it before it got ran over. She immediately checked the emergency contact on the ipad and my wife met with her to pick it up. What an angel of a woman. She also gets 5 stars, but I digress...
I expected the ipad to be a total loss. As far as I know, the rain alone could have killed it because I didn't know how this case would handle any kind of liquids. And then I was sure a cheap case wouldn't be able to handle flying off a vehicle at 45mph and landing in the middle of the road. But let me tell you, THE CASE BARELY HAD A SCRATCH ON IT. The ipad is 100% perfectly fine. The case protected the ipad from the rain and even from my stupidity. The corner of the case had clearly been the point of impact. It was dirty on that corner, which mostly wiped off. The plastic hard shell part of the case had separated slightly, which I just had to squeeze the corner back into place and then we were good as new. My daughter never even knew it had been gone.
This is the most positive 5 star review I've ever given. I'd buy 100 more of these if I had 100 more ipads. Don't even think about it, get this case and enjoy your piece of mind that it will be well protected... even when dad forgets it on top of the vehicle.

Great purchase! Will Buy Again.
Color: A01-Colorful Pink
Best purchase for my childs tablet. They are able to carry it like a cross-body with the strap or hold it with the handle. The handle is able to rotate in different directions to set up hands free on a table either longer way (landscape) or short (portrait). It has a hard case then the thicker silicone surrounding it. It does a great job protecting the tablet. My little one has dropped it plenty of times and it's still in great condition.

So far, indestructible.
Color: Coral Orange
Such a good case! For a 6 year old that isn’t exactly gentle with devices, it’s perfect. The swivel kick stand is pretty versatile, easy to find a comfortable angle to see the screen no matter which weird position your kid sits in. The color is really nice, the orange is soft and very pretty.

Sturdy just wish it could be adjusted to hang shorter
Color: A01-Colorful Pink
Very sturdy. Love the colors, easy for my 4 yr old to handle and use.
Wish the length could be adjusted shorter for her though. When wearing, it tends to hang low by her knees.
