Review on IPazzPort KP-21SM Mini Bluetooth Keyboard With Touchpad, Backlit Wireless 2.4G USB Dongle For Android TV Box/FireStick/Laptop/PC - Latest Upgrade by Jeff Wieczorek

So far it works okay. Wasn't difficult to link to nvidia. It is built a little flimsy. The battery cover is loose. The charging port is too tight so you have to struggle to plug in the cord. As far as being upgraded. I had a non bluetooth version years ago. It worked great. I almost forgot the backlight colors are too much. The only one you can read is green. Guess just plain white light would be best which isn't on this one.
