Once a couple of years ago I was at an used vac-shop and tested a Dyson. Let me tell ya what, it was a real smoke wagon! After that little episode, I had to sit for a while just to catch my breath. It gave me one of the worst headaches I'd ever had in my life, which carried on for many more hours, to the point that it nearly even ruined my sleep. The next morning was awful, it felt like I woke up in a morgue. I was cold and had the rigors all over, and from that moment on, I vowed never again to desecrate a fingertip with the touch of a Dyson!
