I have the thin large one. It was from Amazon on a Prime day deal. It was under $15. It's nice but has to be charged or plugged in. That is a hassle for the most part. I use the Crayola one the most. It's really all I need. No cords or charges and the perfect size for a 8 x 11 1/2 paper. I haven't changed the batteries in it since I've had it. Worth having a back up. I heard they were being discontinued.
