it arrived with the 7 head fixed to the motor broken from some impact on the box. The piece that pushes into the motor, (the black bit and the white plastic piece were broken) had been wedged in (had to use pliers to get it out). I was going to send it back, unfortunately as the piece in the motor end finally came out, it landed on my hot grill I'd taken out just prior. As such I had to use both black and white pieces off the 3 head to at least have the main 7 head working.
