I picked up the Mr. Buddy Heater for camping trips and emergency backup heat, and I have to say, it’s one of the best purchases I’ve made. This little heater throws out an impressive amount of heat for its size and works like a charm in cold conditions.Heat Output & PerformanceI was honestly shocked at how well this thing heats up a space. It warms up my tent, garage, and even my small cabin in no time. The heat output is evenly distributed, so I don’t end up with just one super-hot spot while the rest of the space stays cold. On the highest setting, it’s seriously powerful, and I’ve used it in near-freezing temps without any issues.Portability & Ease of UseThis heater is super portable and lightweight, which makes it easy to take anywhere. The built-in handle is really convenient, and it doesn’t take up much space. The piezo ignition makes starting it up effortless—just turn the knob and press the button, and it fires right up.Safety Features & ReliabilityI love that it has built-in safety features like the oxygen depletion sensor and tip-over shutoff. It gives me peace of mind when using it in enclosed spaces (with proper ventilation, of course). I’ve used it for hours at a time, and it runs reliably without any weird smells or issues.Final ThoughtsIf you need a solid, portable heater that delivers serious warmth, it is worth every penny. It’s easy to use, kicks out a ton of heat, and is perfect for camping, emergencies, or working in cold spaces. I’d definitely recommend it to anyone looking for a reliable and efficient heater!

I purchased this Mr. Heater unit for camping and emergency backup use. I try to test mechanical objects asap after receiving them to make sure they function correctly. This definitely does function as described, lit easily, intuitive controls; low heat is steady and reliable; high heat is solid. Ran it for several minutes on each setting with a 1lb bottle with no issue. I have a hose/filter to connect a 20lb propane cylinder but have not tested that yet. Will report back if there are any issues. So far, it works as advertised and CAN be used indoors even though the instructions say you should not (likely due to liability issues). There are multiple youtube videos showing people using this heater indoors next to a CO meter and it burns very cleanly with no issues. Overall it's a good value and puts out heat!

This is a great heater! You dont ever need to be outside in the cold. This will keep you warm and get the job done. There is also an adaptor you can buy to refill the little green bottles for your larger propane tanks. By doing this it will save you money by refilling the green bottles instead of throwing them away.

I have it in my old barn for the dogs. Has a good tip over cut off. Puts out a lot of heat but does use propane quickly. I use it with a 20 lb tank and it goes through that in two days on low.

Extremely made and awesome to have in a hunting blind on a cold day. Easy to use and very powerful for its portable size. Highly recommended.

We are living in a ten-man tent and it is getting very cold since it is January. This little workhorse is keeping us comfortable and it’s been super-easy to use. To conserve fuel we use the “low” setting and haven’t really needed more, despite high winds and my inability to get the tent closed up a little tighter. Very reliable and highly recommend.

Lo utilicé en el Nevado de Colima a -1°C al exterior, dentro de una tienda para 6 personas, en minutos estabilizó la temperatura con ventilación obviamente. Como comentan, un tanque en mínima potencia dura 3 horas, llevar 2 tanques para una noche comoda

I found this product on amazon.ca and it was the lowest cost I could find in Canada. It worked great I used it ice fishing and was able to sit in my tee-shirt in -30 degrees celsius in my pop up ice shack. The little bottles last a fairly long time and are easy to transport.However, I bought an attachment cord to hook up the heater to a 30lbs propane tank and it was awesome. No more wasting bottles and the heater would work for a long time I use it camping, hunting and fishing and it works perfectly.It has a shut off incase it tips over and I used it in a confined space with a carbon monoxide detector overnight and the detector never went off once. There are other models that come bigger and with a fan which would give you more heat but I find the heater is nice and compact and easy to store. It lights easily and stays lit with no problems. I have had buried in snow cleaned it off and it works fine. I have even accidentally left it outside in the rain and it still works great. This product is well worth the money and works great in a small space.I highly recommend this product to anyone looking for a portable heater. It is an awesome product. Reliable, durable and compact. If you are wanting something bigger the Mr.Heater does have a bigger model.
