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

Worth it!

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!

Great quality case and keyboard
Color: Purple, Color: Purple
Super good quality case, I was actually surprised since it’s such a good price. It fit my 10.9 inch perfectly! Keyboard has magnetic attachment to the case which is super handy, and it connected with Bluetooth seamlessly. Keyboard isn’t silent, it’s on the louder side, but not too loud at all and it doesn’t bother me at all because I prefer clickier keyboards. Oh also something that’s really cool is that you can change the colors of the keyboard, love that!
