Amazing!
Color: Midnight Green
The Hamile Keyboard Case for iPad (11th & 10th Generation) is a practical accessory for turning your iPad into a more laptop-like setup. Designed with a detachable wireless keyboard and protective case, it’s aimed at students, professionals, and anyone who types frequently on their tablet. One of its most appealing features is the 7-color backlit keyboard, which makes typing easier in low-light environments while also adding a customizable, stylish look. The backlighting can usually be adjusted in brightness and color, making it both functional and fun to use. The keys are generally responsive and comfortable enough for everyday typing tasks like emails, notes, and document work. The case itself provides decent protection for the iPad, helping guard against scratches and minor bumps. It also holds the tablet at a stable viewing angle, which is useful for video calls, studying, or streaming. The wireless connection is typically simple to set up via Bluetooth, and the keyboard can be detached when not needed.

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
