This does work just as described. I thought I had taken a picture of it lighting up the keyboard.

LOVE these laser projector bluetooth keyboards!!!!!
They They really are very cool and convenient, they are compact and light and easily fit into a small bag to carry them with & they can't be used on basically any flat surface & they work really well, I have bought 4 of these to go with some of my devices & I haven't experienced any issues with them so far!.

Works great. So much fun to use! Connects with Bluetooth easily.
