I've just bought one, wired it into the 12v on my controller as per the instructions and although I get a green light for power the motor wouldn't move at all.
It does look a good bit of kit but not a good start, I've returned it to the shop.
Also of note is that the instructions state that for the peco standard turntable lk-55 you need to add the spacers to the mounting brackets, this is in fact wrong and results in the gap being to big and not in contact with the turntable pole.
The instructions are also poor and vague!
