Customers are satisfied with the heat settings of the space heater. They mention that it puts out great heat, can keep warm three of them sitting next to each other, and has more than enough heating power for the task. The unit heats well without the fan, and is portable enough to use for a garage work site or camping. Some customers also mention that the heater is powerful and can run on 2 burners for 8 hours. The operating flexibility allows you to heat one or both elements.

Bought this to keep our plants warm we had placed in the patio. I also purchased the stove fan as well. The 2 1lb bottles lasted 6 continuous hours. Also ordered the quick connect hose so I could attach the 20lb bottle. This heater puts out some great heat and look forward using it in the garage or patio when the weather gets nippy. Wished I had bout this years ago to get away from the electric heaters.

I got this for a friend of mine that was using kerosene to heat. It lasted 10 times longer than the kerosene and the heat was much better and no smell of kerosene. He is so happy with this and I was very impressed with it also. I would recommend it for anyone that needs a good heat source.

This heater worked well. I purchased the model with the blower (convection style) but got the "No Fan" (radiant) model. This a bit disappointing thus the the one star deduction.

Used the Big Buddy to heat my garage so that I could tackle a project on a cold day. It raised my 2-car garage temperature from 44 degrees (F) to 52 degrees. Doesn't sound like much, but that 8 degrees made all the difference so that I had comfortable conditions in the garage while I worked.

1.0 out of 5 stars Got it fired up once
Reviewed in the United States on January 14, 2024

Hooked up to full 20 pound tank. Took many many many many times to try and light it and it would not light. Had to use butane lighter to get pilot light burning & still not sure what I did to get it lit. Apparently there is no provision to purge air out of a brand new hose from the 20 pound tank to the heater. Bought some 1 pound bottles and put them in. Ran it for a while. Maybe that primed the system with some gas. Hooked up the 20 pound tank again and after quite a while finally got it to light. It ran well. But trying to get it to light and fire up the pilot light, unacceptably ridiculously long time. Going to try & figure out how to get pilot light to work without turning the piezoelectric igniter hundreds of times.
This ought to be advertised as one use disposable.

You'll need to buy 4 or 6 12v CPU fans and build something to push heat. Otherwise it has never failed. Be careful the ignitor will not work below -5 degrees so keep it on low overnight.

After 2 years our little buddy failed. Wouldn’t light. As we needed one with more heat we are now trying out a big buddy. Hoping for better longevity. Theybreally should last longer than two years?
