I am not sure how it would work because I didn't get a 'proof of purchase' or anything from buyapowa.
My controller is dead Got to do a bit of testing but I'm pretty sure it's the wiring going into the controller that's at fault. If so I'll be contacting Gerbing about a replacement since they're only 2 months old.
I found out that they have charged £120 to my credit card - probably because I joined really early when the price was fairly high + postage. Fingers crossed refund the savings, and more importantly deliver the darn mittens...!!
