I don't know what model it was, but my good friends purchased a Dyson heater that looked just like this (around $600). They tried it out for a while. They returned it for a full refund (was a promotion, trying to get people to try it out, offering full refund within 30 days, no questions asked). They then went to Bunnings and spent $80 on a heater that worked better (AKA produced more heat, faster).
