As the title states, this is a fantastic heater when it decides that it wants to work. Judging by the other reviews it's a good possibility that we received a faulty product. This Mr. Heater was originally purchased for activities such as hunting or camping, but has been used for other things as well. It has really come in handy when the electricity is out during the winter, which seems to happen alot around here, and we don't want to have to use the generator all night long. We may have just gotten a bad product, but sometimes our heater won't stay lit. It will turn on and act like it is going to work, but fifteen minutes later it just shuts itself off. It heats up a room really quickly and keeps it a nice comfortable temperature. It has different settings so you can adjust it to your liking. I love that it has the safety feature on it which makes it shut off if knocked over, though we haven't tested it out. Overall I like this heater and it seems like an isolated incident, but make sure you test it out right away so you don't get stuck with a partially functioning one like we did.
