Product review (5 stars): Only very minor nuisance is the internal fan stays on a while after you turn it off to cool down the innards
This is the second one we have bought (2 different houses) - don;t have them long enough to talk about longevity, but at 1800 watts its as powerful as you can get for a 120 volt appliance. Enough choices of power, not sure how accurate the temperature control is, but I don't use it anyway. Only very minor nuisance is the internal fan stays on a while after you turn it off to cool down the innards.
