    • Wonderfull little heaters.
Color: Red Style: Heater
I love buddy heaters! Have used em for ice fishing in interior Alaska, to hunting in Montana. They are easy to use, pack some what light, and keep you warm. I also love the safety features that they have with their auto shutoffs. Quality product that I beat the piss out of and it keeps working! You can also hook em up to a 20 pound propane tank if needed (with the extra hose). ... show more

    • Great little radiative heater
Color: Red Style: Heater
The thing to know about this heater is it throws off a lot of infrared radiation, which is the primary mode of heating. It is like having a little portable Sun with you. Like if you go outside and it is cold and cloudy, you will feel cold. But at the same outdoor temperature and the Sun beating down on you on a clear winter day (if you have clear winter days were you live), you will feel a lot warmer. A fun little thing to do if you have security cameras with night vision, light this up in view of one of these security camera's at night. It is brilliantly bright and everything in the line of sight of the hot plate on it nearby is brilliantly lit up. With the naked eye at night, you will just see a dim red glow, but the security cameras will see a blindly bright light as it is in IR night vision mode and the black body radiation is primarily in the infrared spectrum. This means when you are outside, basically regardless of conditions, as long as the conditions are good enough for this to work, it will be heating you up. You can even say leave this outside your tent and as long as you are setup to let the infrared light in, it will warm up the inside of your tent and any infrared light hitting you from this will warm you up, say you are laying there in your sleeping bag. It is almost like magic as most people are used to thinking about heating in convection terms while this primarily operates in black body radiative terms. I am not saying sit out there butt naked in the snow with this being your only device to keep you warm, but it is a greet supplemental heat source to help you keep warm when you are doing something sedentary outside in the cold. The one gripe I have about this is the flame is unstable and noisy on the low setting. This works best at the high setting anyway, so probably what you want to do and just forget about the low setting. If you use this with a larger tank with a hose, you may want to plan to shut the main valve off on the larger external tank a couple to a few minutes before you are done using the heater so that there is time for a pressurized hose to purge. As this only lasts a few hours on a 1 lb tank, you can quickly end up getting into using larger tanks with this. ... show more

    • A Great Value With Excellent Performance.
Color: Red Style: Heater
We recently returned from a tent-camping trip to Vogel State Park in the North Georgia Mountains. (Our tent is a 9x7 Coleman Dome Tent) Prior to going, we learned that the temperatures would be dipping down into the high 20s during the overnight and early morning hours. Since we had never camped in temps that low, we decided to purchase the Mr. Heater based on the reviews that we had read. As is the case with all reviews, you have to take the good with the bad and I've found that I search out the bad, as well as the good, so that I may be aware of any potential issues. In our case, our issues were very minor, and for the most part the unit performed flawlessly. Keep in mind the tent size and square footage when making your purchase. We felt that it was more than adequate for our tent size. PROS: Ease of use. The propane cylinder is very easy to install and remove. Keep in mind that the cylinders range in cost from about $3.00-$6.50 depending on brand. We camped for three days and used three cylinders (the amount of cylinders that you will need will depend on how long you use the unit. One night we needed it for about 5+hours, so it was necessary to change during the night.) We kept the unit in the tent with us, but made sure that it had necessary distance away from our air mattress and the tent side walls. Though the unit comes with an emergency shut-off in case of low oxygen, we made sure that our tent had adequate ventilation while operating the unit. Primarily, we unzipped one of our windows slightly, plus the top of our tent is mesh and covered by the rain fly. The ignition was very easy most of the time, however, if there was anything remotely close to a con, it would have to be that sometimes it was necessary for us to press the control knob 5-10 times to get the pilot to re-light. This causes a pretty loud "clicking" noise in an otherwise quite campsite. Other times, after two or three presses of the control knob, the pilot would fire right up. The unit is very portable and light. The heat is very substantial in low or high setting. As I previously stated, it was more than adequate for our 9x7 dome tent. There is nothing to put together and the directions for use are very easy to comprehend. Follow the directions and be sure to do an initial test of the unit prior to using in a tent for the first time. It will produce a slight odor as the directions state, but it will soon dissipate. CONS: Sometimes it was necessary to push the control knob 5-10 times to get the pilot light to fire. Other times it fired right up during the normal 1-3 pushes. There are only two settings: low and high. While this is okay with us, others may prefer more of a variable type of setting. ... show more
