Good quality case with a good price!
Color: Pine Green, Color: Pine Green
I love this case! I have used the case forever now, I wanted something to cover my screen when not in use I have had my iPad in my purse or in my car my kids have handled it and my iPad has stayed in perfect condition. I just started using the key board. I don’t like how flat the keyboard is but it’s a good keyboard when comparing prices it does what it needs to! The magnetic closures are strong! I have some off brand pencils but have not tried the slot that holds a pencil yet but looking at it I can see how it could hold a pencil better than a Samsung tablet I have does as the case to that one the slot is on the outside and does not hold the pencil well.

Great case and keyboard
Color: Light Pink, Color: Light Pink
Omg. I LOVE this case and keyboard. It works so well and makes my iPad seem like a computer. It’s connects really well and I love the keyboard colors! I’ve been using it at work and it has been so great on saving notes and writing emails using the keyboard etc. And it’s very sturdy!

Made well but function is challenging
Color: Dark Cherry
I’m not so sure I really like this over all. The keys on the keyboard are nice, not mushy at all, very clear and functional. And the size of the keyboard is fine. It’s not full size and I didn’t expect it to be. But what I can’t get used to is how floppy the rest of it is. It won’t sit well in my lap, it must be on a flat surface to function at all. I find that very frustrating. The grooves that prop up the ipad won’t hold it if you move it at all. The keyboard must be unattached, moved and reattached to close up everything securely. Also it is heavier than I expected. The quality is good. It is not cheaply made. The color is just what I wanted and expected from the description. I’m giving it four stars instead of three because it is made well, but it’s mostly form over function. Edit: I returned this product and ordered a keyboard with the swivel holder for the ipad, much sturdier and steadier.

Purchased for the new iPad Pro size 11 inches
Color: Pine Green
I have a feeling that the people having issues may have the older model of iPad Pro! For the new model currently sold by Apple, the fit is good. The magnets & keyboard work perfectly. This is a great deal considering a lot of cases and keyboards cost just as much separately.

A bit disappointed
Color: Pine Green
Needed a new cover for my Ipad 11. This product had a good price, options for colors (I picked the green) and shipping was fast. When it arrived out of the box I was disappointed. Putting my Ipad 11 into the case was a bit harder than I expected. Once in, either the top or the bottom would not sat seated in the case. The backlight is nice, but you have to charge the keypad and ipad separately. I returned this because you have to physically move the keyboard to either use it or close the case or get the Ipad to stand. So, when closed the keypad sits right under the Ipad screen. When you open the case and want the ipad to stand, you have to physically slide the keyboard towards you or down to the bottom of the case. This then allows you to fold the upper portion and stand the ipad upright. You have to reverse this to actually close the case. What all this means is two things for me...this setup takes more deskstop space and a few more movements to get everything setup.
