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.

Highly recommend!
Color: Pine Green
I love the color, the feel, the weight, the functionality, all of it. The keyboard connects so easily and even has instructions on the back for enabling certain functions. I like that the mouse pad actually works, and well, and I can easily take notes as I would a laptop. I kind of want to buy another as a backup, just in case, because I love this so much! Oh, and battery life is great on the keyboard! I made it through a week long conference on a single charge.

Very Plastic Feeling and WILL Scratch or Break Your Screen Eventually
Color: Pine Green
TL;DR: (To Long Didn't Read)
Keyboard: Really Flimsy Plastic, Comes in DIRECT Contact with Screen, WILL Scratch and or Break Screen
Case: Makes iPad Fatter and Bigger than a normal Business Folio, outer layer has nice rubber feel, When
closed it does not turn off your screen.
I have the Magic Keyboard for my New Ipad Pro 11 inch M4 and my largest complaint is that you can't fold it down and use it in "normal" Tablet mode.
I wanted to get something that would let me keep it in a case and use it in a flat mode to draw or play games. I stumbled upon this and was super excited. It has a wireless keyboard and could fold in a lot of ways.
I was WAY WRONG. The keyboard is nothing but cheap hard plastic and is very flimsy and comes in DIRECT contact with the screen which will eventually either scratch or break your screen. When closed and folded it makes your SUPER THIN tablet larger and thicker than MOST Business Folios. It also does not turn your screen off.
I will give this product 2 stars because the case itself feels really good on the hands. They used a rubber material that Apple uses on their Smart Folio Covers for their iPad. Also, the product idea itself is amazing just very poor build quality and not protection for your screen. I guess that is what you get for your $30.00
