The little box of electronics on the end of the keyboard looks minute. Even if bendable, you'll need darn good eyesight and incredibly steady hands.

I've got one very similar. It's all SMD's that are barely visible. I only found one 'glitch' which just kept crashing it.
Also, 'cos of the way it was stuffed in the box, it won't roll out totally flat so there are creases in it which cause other adjacent keys to trigger.
I've nailed mine to a flat strip of pine to solve this problem.
On the plus side, it has some nice warm tones and the drums sound good.
Verdict  -  Don't buy one. They're pure gimic.

hmm...you know, i keep wondering if there is a way to use just the keyboard to a lot of these things. i mean, not specific to this model...but, when you look at the pcb, and you can see where the solder flow is to the keyset. that may be a way to use a keyboard to control a homebrewed synth. especially for a keyboard that is un-bendable.

Agreed.. Wait until nobody else buys them and they start turning up on ebay for £4.99... Then it doesn't matter too much if you fry a few of them ;)

Are the chips real chips, or just black blobs?  Any numbers on them?
