## Description

18,000 BTU Big Buddy Portable Propane Heater (No Fan)

Review: All it's not Well... - This product can not be sold in Europe, the product has pass the tests to get the CE certification, it was sold to me in Portugal, trought desertcart.es by All is well company it was defective, they offered me to buy a new one with a 50.. euro credit, now the European company that could fix it refuse for liability reason, I am stuck with a large use less purchase, All it's not well...
Review: Quality product, easy to use, just a bit pricey. - Very easy to use, made well. Doesn't get hot at the bottom, making it pretty safe for indoor use even on rugs or carpet, although definitely avoid that if possible, just in case. Lights easily, tip over safety works well. Doesn't tip easily in the first place. Solid but not heavy. Hooks to bigger tanks for longer use. Puts out a good amount of heat for the size. Guard rails are pretty sturdy. Runs off 1x or 2x small 1lb tanks. 2x is needed for use on High though. Overall a very good portable propane fueled infrared heater. I would definitely recommend. Only 1x CON & that's the price. I think $200 is high, but I'm happy with the product itself.
