Bests & Worsts Reviews from Amazon

I bought this thinking, what a great idea, air purifier, fan, heater. Sure it's a little pricey, but Dyson is a quality brand. I had opted for the payment plan, by the 4th payment, it stopped working, flashing an H2 code. I've since read alot about this code, and most have had no luck dealing with Dyson direct (the window is closed for return through Amazon). Just made the last payment today on a $400 product that is now just a stationary fan on a good day.
