    5.0 out of 5 stars Solid small space heater
    Reviewed in the United States 🇺🇸 on December 20, 2022
    I was using my brother's the last couple years and decided to buy my own. It has been a blessing this year when I been out hunting in a ground blind during the cold days. It will also be nice ice fishing so I can bring out my son. The only thing I had to do is attach a piece of wood to the base to make it more stable. Also the base it has doesn't work well with 1lb propane bottles that have the plastic bottom piece. Get the berzomatic brand propane bottles because the base is all metal and sits in the heater base well.
