“This heater works exactly as advertised! It warms up my small cabin quickly, and the safety features give me peace of mind when using it indoors.” Mike R.
⭐⭐⭐⭐⭐ Perfect for Camping and Emergencies
“I take this on all my camping trips, and it keeps my tent nice and warm, even in freezing temperatures. It’s also great for power outages!” Sarah W.
⭐⭐⭐⭐☆ Good Heat Output but Propane Usage Adds Up
“It puts out a lot of heat, but a 1 lb. propane tank lasts only about 3-4 hours on high. I recommend getting the hose adapter for a 20-lb. tank if you need longer heating.” James K.
⭐⭐⭐⭐☆ Safe and Easy to Use
“I love how simple this heater is to operate. The auto shut-off feature works well, and I feel safe using it indoors. Just wish it had a built-in fan to spread the heat more evenly.” Lisa M.
⭐⭐⭐☆☆ Great for Small Spaces, but Be Mindful of Ventilation
“Works great in my garage, but you have to crack a window for ventilation if using it inside. Otherwise, the oxygen sensor will shut it off.” Tom D.
Overall, users appreciate the strong heat output, portability, and safety features of the Mr. Heater Portable Buddy Heater (MH9BX). While some mention propane consumption and ventilation requirements, it remains a top-rated choice for camping, emergency heating, and small indoor spaces!
