I had to pop into PB for a warranty-related repair a week or so ago and their initial thinking was to tell me that if my warranty claim was rejected they would tell me how much it would cost before repairing...I'd already explained what the issue was and it was clear that it was a manufacturing defect (the charge unit had come out of the scooter body with the cable).
I mentioned that this was a Warranty issue and they said they would determine what was and wasn't accepted. In the end it was an easy fix and was done there and then, but it led me to be more than a little concerned if I had a REAL problem with my scooter...
