Easy set up

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.

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.
