Just wanted to say on this forum, that last week while on holiday in the van my rollers on my powerwheel broke I phoned the company who without hesitation sent me two new rollers, As these were modified from the originals the technical department helped me over the phone change them> The one Iremoved had its bearing stuck on the facing plate and made it impossible for the new one to fit, It was only when I removed the other side that I could see the what was wrong, however powerwheel were only to happy to talk me through the job, So a big thank you to all at Powerwheel, where 5 year guarantee means 5 years
