Product review (1 stars): Mine was defective
We bought this at a local department store. We were very excited about this and it seem to work very well the first time. After  emptying the pot and putting the pot back on refilled, after about two minutes I heard a buzzing noise and 30 seconds later the unit shut down with an  internal overheat error.  I noticed on the bottom of the unit there is a fan which I never heard come on.  It could be that the buzzing sound was the fan trying to run but apparently it is defective. Since their warranty requires you to pre-pay the postage to return it to them just so they can fix it,  this one's going back to the store.
