As with any purchase be an informed customer and know 'who' you are dealing with. My elderly neighbor made a purchase out of the back of a trailer and gave them cash without getting a receipt. Many very legitimate dealers who are fully authorized by the manufacturer and will do the warranty service for you do have mobile demos. Just make sure the receipt has a name, address and phone number "printed" on the receipt. If ever in doubt or anything, please ask before completing your purchase.

We like our 'CZ Infrared' heater so much we just ordered another one. The www.czinfraredheaters.com has a season end SALE.

I just love my CZ Infrared portable space heater. Sure my electric went up but I still saved hundreds on my overall heating bill each month. It paid for itself in 2 months I would recommend it to anyone.
