Probably the junkiest keyboard ever made. It doesn't have a headphone or AC adapter jack. It only runs on 4 AA batteries. It seems to have only two-note polyphony (most of the time only one note). Although it has two speakers, the output is mono as they are both wired to the same points on the circuit board. The two, smaller, inside "tweeters" are not real. I hooked up a headphone jack to one speaker wires to record direct sound. 10 instruments which are oddly out of tune. It has 29 demo songs (some sound really bad). 10 randomly-named rhythm styles with strange fill-ins (which don't match the selected style and come in at odd times). The drum and keyboard recording sections don't have a click but it is quantized in some way. So, you can't get a usable loop or melody without a lot of trial and error.
