I also bought this set from BBTS, and mine came intact. I really like the the model, BUT....
Mine have similar issues, even though the set is correct: XX-1 and XX-3. XX-2 is a different set, but it is the base. I could not fully connect the two arms and the right leg to the body.
I could not test the audio, because I don't have the AC cable.
It seems like Kids Logic is lacking QC department. So disappointed. For the price of the model, Kids Logic could do much better.
I emailed BBTS. and waiting for response.
