5.0 out of 5 stars Nice Little Heater!
Reviewed in the United States on November 12, 2023
This little heater works perfectly for what I bought it for- to sit out on my covered porch and read on chilly mornings.
I love the compact size, built in carrying handle and ease of lighting it.
I have been using it for an hour or so every morning for the past week and haven't yet used a full tank of gas.
Very happy with this purchase.

5.0 out of 5 stars I like it
Reviewed in the United States on November 25, 2023
Used 4 cans of fuel with this heater. I really love it. Just the perfect portable heat for the work shed, heating up a chilly room, or getting warmed up fast after being outside shoveling snow. I have had no difficulties with the ignition or the heat output. One bottle lasts anywhere from 4 to 5 hrs-ish. But it really varies with type of use. Start and stop or continuous use etc.
