Pretty Color & Lighting
Color: Pink
I found myself needing a keyboard case for my iPad pro (10.5 inch). I stumbled across this one with great reviews. Once I opened the box it arrived in, it lived up to its reviews. The case feels smooth and appears to have great quality. The keys on the keyboard sound like a typewriter which I love. I was unaware that the keyboard lit up but to my surprise the lighting was extremely bright even in the daylight. The weight of the both the keyboard, iPad, and case all together feels as heavy as a FiveStar notebook. Connecting the keyboard to the iPad was the easiest part because once you pop your iPad in the case and turn on the keyboard and press the connect button you head to the bluetooth settings of your iPad to pair them. Performance wise sometimes the keyboard snoozes after a few minutes of not being used and takes a second to start typing again. Besides that it works great when you’re constantly typing. Overall I love the color of the case and it’s definitely a money spent well.

Great product!
Color: Dark Cherry
Was nervous after reading reviews but I have had zero issues with this product. I actually really like it and have gotten so many compliments on the color and versatility of it. The charge on the keyboard lasts so long and the led colors are super fun for those late night study sessions or homework cramming. The case also works great on its own without the keyboard, k like that it wraps around the iPad completely.

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.

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.
