Mr. Heater Portable Little Buddy Propane Heater

Mr. Heater F215100 Portable Little Buddy Propane Heater SKU: F215100

Rated 5 out of 5 by from Great product [This review was collected as part of a promotion.] I bought this to heat a small space. It is just the right size gives off a lot of heat and doesn't use a ton of propane. I like that it works indoors and is safe.

Rated 5 out of 5 by from Easy! [This review was collected as part of a promotion.] I love this little guy! It’s so easy to haul with our gear. The tank is simple to swap out and it puts off a good amount of heat. We’ve used it for camping and I can’t wait to use it in the ice fishing house too!

Rated 3 out of 5 by from Lots of heat, if done right [This review was collected as part of a promotion.] The little buddy heater is easy to use and not to cumbersome. It definitely puts out a good amount of heat. The only problem is that it all goes straight up. If you’re outside you have to get very close to it to feel it because most of the heat goes straight up. If you were in a tent or under a canopy it would probably work more efficiently. I still like this product though. It’s good if you’re camping in cold weather and need something to keep your from freezing.

Rated 5 out of 5 by from One of the best portable heaters I've used [This review was collected as part of a promotion.] The Mr. HEATER Buddy heater is one of the best heaters I've ever used for smaller areas. The heat output is great for hunting blinds and camping. It is easy to use and produces an excellent amount of heat for its size.

Rated 5 out of 5 by from Mr. Heater Little Buddy Propane Heater [This review was collected as part of a promotion.] This little heater is just great. It's portable and easy to get set up. The small size means you can use it in a variety of places. And the heat it puts off will warm a decent sized area. I can't wait to use it this winter when we go camping and fishing. It's going to be absolutely perfect!
