Mr. Heater Big Buddy

I purchased model MH18B in December of 2006. It has never worked as advertised. It goes out after 15 to 20 minutes of use. The low burner won't stay lit. The slightest movement causes the heater to go out. The good aspect of the heater is the fact that it is very safe. To sum up, my experience with this product has been less than satisfactory. Basically this is a great product idea though product implementation is somewhat lacking. I sent an email to Mr. Heater and they responded with a prompt phone call to advise that they know what the problem is and can advise me on how to fix the heater. My opinion, though, is that I bought the heater with the notion that it would work out of the box and not have to be 'fixed'. When the heater is working, it works great and its portability and great heat output are wonderful. Maybe Mr. Heater has incorporated their 'fix' into production units and the frustration I have had with my Mr. Heater Big Buddy is a thing of the past. If the product works as advertised you will be very pleased with the product.
