Bought a Dyson vacuum cleaner in May 2015. After asking Dyson what would be best for me as I have lower back pain, painful neck, arms and shoulder, they suggested the DC40. After 2-3 weeks my pains were worse as it was too heavy and very awkward to maneuver the machine so I called to say I wanted a refund. After a lot of phoning and sending a letter by special delivery, which I had no response I called Dyson who said that they could do nothing. I returned this vacuum to Tesco where I bought it from, who were so helpful and polite and I got my refund in full. I was wrongly informed by Dyson that this machine would be fine for me and that it was light and easy to maneuver. THEY WERE WRONG, and I would NOT buy their machines again.
