I have had this Lasko 5130 ceramic heater for years and it has not failed me yet. Very cost effective and provides good heat.  I have since bought other Lasko products - one of which "clogs" easier and have to vacuum out so it won't overheat.  Lasko does have a link on their website (unlike DeLonghi) where you can check a unit you are having trouble with and check for a recall.  They are quick to mail fedex lable and/or box and label.  A good company which seems to stand behind their product.
