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!
