I’m absolutely loving this iPad case with the wireless keyboard and mouse! The first thing that caught my eye was the gorgeous glittery blue color — it looks so stylish and unique without being over the top. The case feels sturdy and protective while still being lightweight and easy to carry. The keyboard connects quickly and types smoothly, making it perfect for work, school, or just browsing online. The wireless mouse is a great bonus and makes using the iPad feel much more like a laptop. I also love that the stand holds the iPad at a comfortable viewing angle for typing or watching videos. Everything charges easily, setup was simple, and the battery life has been great so far. Overall, this set completely upgraded my iPad experience and looks beautiful at the same time. Definitely recommend if you want something functional, protective, and cute

Fits new iPad perfectly, relatively easy to get in & out of holder. Keyboard is easy to use and satisfyingly clicky. Mouse and keyboard synced up with the iPad immediately, no issues. Sparkly color is Kermit-green and exactly what I wanted.
