The Mr, Heater Big Buddy , A great safety blanket!

I just bought two more of these Portable Mr Heater Big Buddy heaters to keep on hand for power outages. I’ve used them for years and have yet to have one to fail. They’re a great piece of mind knowing you can stay warm as they do a tremendous job. I use a 20# tank with hose run outside of the house for safety. The one pound canisters do just as well, but you burn though them pretty quickly. But either way they keep you nice and warm. Add said that it came with hose and filter, it only came with heater and hose. The filter is only needed if you use the 20# propane tank, but they’re pretty inexpensive. SAMs price beat everyone else’s price even without the filter . They’re very safe to use and extremely fast to get out started in a power outage. If using an optional 20# tank, you must have the tank outside your house as per directions. I love them, and I’ve yet to have one fail after several years of use. SAMs Mr. Heater Bug Buddy still comes with the fan than runs off 4 C batteries or 6 volt AC adapter which I understand is being discontinued, Not sure on that, But have read that from other sellers. I highly recommend the Big Buddy, very inexpensive piece of mind, and the best place I’ve found to purchase them is SAMS CLUB!

Very good heater

I've been using this heater with excellent results. I originally bought a smaller model, but ended up needing to purchase the fan and adapter hose separately—both of which are already included with this one at a much better value. The fan even comes with an adapter so it can run on batteries or be plugged in. Overall, this is a great heater at a fair price.

Worth every cent

I’m using the heater equipped with two one pound propane bottles in my two stall garage that is very well sealed against cold weather. I was concerned there might be CO gas from it so I installed a precision CO meter near it to check the levels produced. After 30 minutes of running it on max heat the CO level registered 00.00 which means to me that as they advertise, it’s safe to use it indoors.
