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!

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.
