I bought one from German eBay, sounds fine and the midbass has a lot of thump! One thing though, I can't get the "+3" leds to lit no matter how high levels I use for the input. At least it looks like they should lit as all the 4 leds can be lit constantly with high levels, but not the last ones.
Got this with me on my weekend trip to Lapland. Oh boy the afterparty on the street with this thing!

Though it was hooked up to a mp3 player with a loong cord and not enough output for the leds to flash properly
These girls were all over it!
Any tips for the deck motor? It spins all the time when power is on!
