Cute, convenient, and definitely needed! I use it every day to carry my emotional support device The keyboard case is sturdy, easy to use, and makes it so much more convenient to take my my girl everywhere. Extra added protection! (I’m clumsy and my iPad has fell quite a few times!) the keyboard works great, I typed a lot of emails and docs! Very happy with this purchase!

Great quality case, keyboard doesn’t work as intended

Color: Dark Cherry

Case is fine and good quality but the keyboard doesn’t work as intended. Bluetooth connects great but the keyboard is formatted incorrectly. For example, when I try to use a dash, it puts an apostrophe instead. I have no idea how to reformat it myself. I’d love just a replacement keyboard

Great buy! Worth the money and the color is nice. The keyboard works, some buttons I haven’t figured out but for the most part it’s worth the purchase!
