I bought this keyboard case for my new iPad 12.9, to make sure everything is fine I tested the keyboard to pair it with the iPad. Surprisingly very easy to set up. Also, I tested the keyboard sync with my iPad, a few hours later I can't stop typing now. The keyboard backlight is great, it has a multicolor mode and another brightness mode to adjust, I really enjoy typing. The intelligent touchpad is very easy to use, simple and straightforward to control my iPad cursor, zoom in or out when browsing a website. The case is very thin protects my iPad very well. Once I was out with my friends, a man jumped out and I had an accident, then my ipad fell down with the case, thanks for the case, I checked my ipad from front to back, everything is fine. The battery may not be fully charged when I received it, it may be partially charged but it will still work for a week.
