I LOVED these heaters.  I live in an area that can get very cold at night.  We purchased two of these heaters and they warmed up our seating area nicely.  Now don't get it twisted, it does not give you as much heat as inside your home but you can put on a light weight jacket and enjoy your outside patio area in comfort.  I'm glad we made the purchase.  Also, some reviews talked about the orange glow, that does not bother us.  Our photos came out beautifully under the orange glow.
