Great heater
Review by Chad

Use this one in the garage. Warms it up enough to do anything in the winter months in the garage without having to be bundled up. And is small enough to put out of the way when not in use.

Review by Richie

This heater saved my butt, and my campers too. I was traveling out of Wyoming in the camper for work in late October during a strange cold snap. Since the camper was not winterized the concern was freezing up the plumbing and tanks traveling through sub zero temps. The furnace in the camper was struggling and the batteries were wearing down. Stopped into Wal-Mart bought one of these and the camper was suddenly tropical inside. Toasty warm and not setting off monoxide alarms at all. Stayed above 70F easily in 5F blowing snow weather in Wyoming. Thanks Mr.Buddy hope I never have to use you again!

Review by CHRIS

I give this product a 10 out of 10 for durability. Mine decided to jump out the back of the truck while we were going down the highway at around 70 mph. We didnt notice till we got out to our duckblind that it was missing, so on the way home we found it on the side of the road. I put the tank in it and it fired right up. I was very surprised since you could tell it skipped down the road about 60 feet.

Saved my life
Review by Greg

Some time ago I was hunting in Michigan's upper peninsula. The night before the opener of rifle season we had a significant snow storm and the temperatures plummeted. I was hunting off a river system that was only accessible by boat. On the morning of the opener, as I was exited the boat flipped next to a beaver damn. The water was deep and I went completely under. I managed to tip the boat upright, secured my gear and crawled through the snow to my blind....completely soaked. Once in my blind, I fired up the Mr. Heater. was able to get my cloths dry by the end of the morning. Where I was hunting, there were no roads, no cell coverage and the closest person in my hunting party was across river about 2 miles away. If the Mr. Heater had not worked as intended that morning, I am certain I would have died of hypothermia. Great product. I don't hunt without it.

I bought the Buddy heater for my motorhome and am very impressed. Was able to get it started with easy instructions and it heated my 23 foot motorhome within minutes.!!!
Would highly recommend this to everyone especially women. Easy to start up and easy to handle.

A great purchase for the money should have done it long ag.
Review by James

I like the buddy heater. It heats my deer house when it was 30 degrees today. My only complaint is that on low it makes a sputtering noise. I don't know if this is normal or not. it doesn't seem to do this on high though. Pricey!! I don't think so how much is comfort worth, sitting in a freezing hunting shack or sitting in one that is toasty warm. on low it used a one pound cannister about six hours. Thats not bad. I will recommend this heater to my friends.

One of my best purchases ever
Review by Andrew

This thing is so worth the money. I've owned it for roughly a month now and it's already payed for itself. Long story short I had gotn my diesel truck stuck in the snow and left it sit overnight in 0 degree weather i went out the next day bought the buddy heater set it under my oilpan on high and my truck started within an hour without this it wouldn't have started at all and I would have had to pay for a wrecker. Now I'll have it for camping and hunting. Definitely a must buy if you live North!

Outstanding product
Review by chris

I lost power and I have a Generac backup generator but it will not run a heat pump system. We had recently had problems with our 20 year old gas logs and was not available for use. I bought my Buddy portable heater about five years ago for my hurricane emergency kit and did not know if the Buddy would put out enough heat to make a difference. it was 25 degrees outside and I placed the heater in the living room. I was surprised to see that it keep our house above freezing until the power company got the power restored. it really puts out a lot of heat. Easy to operate. Just follow the directions printed on the back.

Excellent product
Review by Carl

Bought one 7 yrs ago on sale to try it in my hunting blinds and ice fishing shanty. I was amazed and pleased at portability, ease of use and efficiency of it. So much that I bought a 2nd one to divide use between 4 hunting blinds. A bit pricey but well worth it in long run for the comfort they provide. Nice to sit in a blind or shanty in shirtsleeves. Makes difference of an all day outing or coming home early cuz you're froze. Reliability: One is 7 rs old & one is 5 yrs, never a problem at all with either one. I am very pleased with the quality and efficiency.

Great heater, GREAT customer service
Review by TONY

I've used Mr.heater heaters for many years in the hunting blind and in ice shacks, I finally bought my own Mr. Buddy. absolutely love it. it worked flawlessly for the first month after purchase. Then the unimaginable- it quit sparking. I was besides myself. I finally bought my own fancy heater, and its broken! I called the customer service line, inquiring as to the warranty for these heaters.. gave the CSR my serial number, he informed me that the valve assembly would indeed be covered under the warranty, he offered for me to send in my unit to be repaired or replaced, or if I was feeling "handy" he would send me the valve free of charge. I obliged! I had also in a previous (unrelated) incident ; set a hot torch head down on my heater handle. I asked if replacement handles were available. he responded by asking what color my plastic was, after determining the correct color, He informed me he would be sending the handles along with the valve to me FREE OF CHARGE. I did not expect that, quite generous indeed considering my ignorance caused my handle destruction! I informed Brian that I would do all I could to spread the word of his out-of-this-world customer service. so here's my review!

Terrific product!
Review by Linda

I am living off the grid and bought this to help stay warm overnight. It has proven invaluable and one of the best purchases I have ever made!

Outstanding Product! Outstanding Quality!
Review by Brent

For the simple design, this product is definitely made to last! I was lucky and purchased my Portable Buddy from a local store and was apprehensive at first. However, it was definitely worth it!! The overall construction seemed fragile but I assure you, my heater has been everywhere with me from my hunting blind, to my Bradley Fighting Vehicle when in the field with my unit! it is not backpack portable, but small enough to fit in a duffelbag or car without taking up too much space and on a 1lb propane canister, I get anywhere from 6-7 hours of heat and went from 16 degrees in a 12x12 tent to around 70 degrees! I ABSOLUTELY LOVE this heater and Mr. Heater has my business from here on! You guys rock!
