I looked at a lot of patio heaters and read the reviews.  This seemed more promising than most and I was confined to infrared electric because it is a screened in porch.It is fairly attractive for a patio heater however.  We live in NJ and it has definitely made it possible to sit out on 50 degree days and feel more comfortable.  If you are expecting a lot of heat, this is not your unit, but for an electirc unit, it is not bad.  It certainly takes the chill off.  The cord is a little short maybe 4-5 feet.  It might be more effective to have two units, but the price was too high to consider that and I am not sure about the electrical outlet being able to support the voltage of two units.
