This is the 2nd Mr. Heater Big Buddy we have bought. We loved our first one so much we wanted to get another. My wife stays a little warmer than I do so I fire up my Big Buddy when I am cold. It is able to heat the whole room. I rarely turn it above low. These heaters are the very best thing to have for everyday use and especially when the power goes out!! I bought a hose so I can use it with my 20lb. tank in case I need to burn it for a long time if the power stays off for a while. Here, we lost power for 4 days at one time. These are a life saver. Don't take my word for it,,,,, try one for yourself.

Had a Big Buddy for two years and it was fine heating up a 23' travel trailer. Suddenly, it wouldn't stay on for more than 15 minutes. I see this problem reported by far too many people who've owned a Big Buddy for more than a year. Too darn bad as it is a nice idea!

Maybe it is just a one year and throw it away product?

Got the product thru Amazon dot com and had only one problem with it. It worked fine and did the job well however, it seems the fan motor mount was broken during delivery. Made alot of noise. Called the company direct and they said that they will replace the whole rear access panel with new fan/motor. Free. Wow.

For ones, the product stands up to the manufacturer's description. realy great product, carefuly designed, with lot of thoughts.

I bought this heater to run in the garage during the winter when I wash my car. The heater has no problem heating the garage into the sixties when on full heat. Once the garage is warm, I can maintain the heat at the half setting. I have a standard double car garage to heat. As others have mentioned, the fan doesn't really work that well, but I'm not standing next to it anyway. The purpose of the unit is to heat the room and it does that fine. The only thing I didn't like about it was that the installation of the batteries was difficult. The unit takes two rows of batteries and the springs for the 1st row of batteries gets in the way of installing the second row. They should of staggered the batteries or put them side-by-side. Other than that, this unit works great.
