    • Good quality, highly recommend. Great heat output.
Style: Heater
Works incredibly well. Got it for a homeless friend living in a small camper w/o electricity. Ran it for about 10-15 minutes and it kept the space warm for hours during cold Michigan temps. Highly recommend this.

    • I recommend it for vendors.
Style: Heater
I recommended this heater to a friend and realized I haven't left a review for it yet. This compact heater that sits on a 1lb propane bottle is my best friend for fall and spring vending season events. I use it in my 10x10 canopy to keep me from freezing. It puts out a nice amount of heat, but doesn't push it very far. So I need to be sitting close to the heater. I usually put it a short distance from my chair in the back corner where it won't be in the way. It's completely silent when running. Portable compact size fits in the car with or without the propane bottle. This is the second year I've used it ( fall and spring) and I've had no problems. So 2 years going strong. The ring base is wide enough I don't have to worry about it tipping over on gravel or grass. I get about 6hours of run time with one cylinder. More than enough for a short event ( till it warms up outside). I'm always aware of the placement so nothing burns or no one knocks it over. I always use it with somewhere in the canopy open when the sidewalls are closed for oxygen. ... show more

    • Great little heater!
Style: Heater
The heater went out in my car and is going to cost more to fix than what the car is worth. I am buying a new car in the spring, but needed a way to heat the car through the winter. Bought this heater to keep me warm on my half hour drives to and from work every day. So far we've only had morning temps. in the mid 20's, but I turn this heater on and put it in the car 10 minutes before I leave and the car is toasty warm inside, it actually gets too warm when I'm about half way to work and have to shut it off just so I'm not sweating. Although this is a little bit bigger than what I was expecting, it does the job that I need it to do. I thought about getting an electric heater, but the ones that plug into the cigarette lighter don't even give off enough heat to defog the windshield and the one that hardwire directly to the battery can be bulky, I didn't want to bother with the wiring and they are not portable. The other reason I decided to go with this to heat my car is the fact that it is portable. I have a shed that I use as a workshop and this little heater would be perfect for heating my workspace. From other reviews it seems as though one small propane tank last about 4-5 hours. I cannot really vouch for that yet, but I have used this for three days now, 20-25mins in the morning and 10-15 minutes after work each day and there is still well over half a tank. The only downfall I've found is that when this guy is on it's on, there is no knob to turn it up or down. Oh and the work "ON" is embossed on the on button, not so much of a problem with the heater itself, but really doesn't feel all that wonderful while holding the button down to light the unit. ... show more

Style: Heater
This Mr. Heater Little Buddy has become my go-to for staying warm in various situations. Whether I'm camping, working in the garage, or dealing with a power outage, this little heater provides reliable and efficient warmth. What I liked: Portable and Compact: It's incredibly lightweight and easy to carry around. The compact size makes it easy to store and transport. Powerful Heat Output: Despite its small size, this heater packs a punch. The 3800 BTU output is enough to warm up a small space quickly. Indoor Safe: The oxygen depletion sensor (ODS) and accidental tip-over safety shut-off provide peace of mind when using it indoors. Easy to Use: Simply connect a 1lb propane cylinder, turn the knob, and push the igniter button. It's that easy! Efficient Fuel Consumption: It runs for a decent amount of time on a single propane cylinder. Minor Considerations: Open Flame: As with any propane heater, it's important to use it in a well-ventilated area and keep it away from flammable materials. Not for Large Spaces: This heater is designed for small spaces. It's not ideal for heating large rooms. Overall: The Mr. Heater Little Buddy is a fantastic portable heater that's perfect for a variety of situations. It's compact, powerful, and easy to use. I highly recommend it for anyone looking for a reliable and portable heating solution. ... show more
