This is the best option for your Mr. Heater Big Buddy, and I'll tell you why, and I'll give you a useful tip. USEFUL TIP: When you first connect this, and try to fire up your heater, You will be surprised at how long it takes to light your heater. Because it is 12', and because the gas is regulated to a very low pressure at the tank side of the hose, IT TAKES A FULL 90 SECONDS FOR THE PROPANE TO FILL THE HOSE AND REACH THE PILOT LIGHT. I have tried it seasonally four times now. It is not 70 seconds. Not 80. It is 90. Every. Time. I suggest you connect, open the propane tank, twist your knob and hold it down (prime) for 80 sec before you even try to light it with a new hose. Don't be tricked by a very faint smell of propane, it will take 90 seconds. Have I driven the point hard enough? But only need to do this priming once a season; I can swap out propane tanks and will not need to repeat the 90s priming. PROS OF THIS HOSE: - it has a pressure regulator on the hose at the tank side, which is why it costs more, but the regulator offers a consistent 1/2psi of pressure to your heater. - the low pressure is safer in case of propane leakage in the system (hose, heater, element). You are less likely to have leaks with lower pressure. - the low pressure means that your hose will not leech the rubber oils that ruin so many people's Big Buddy. You don't need a filter at the heater side because there is no leeching. - powers the heater on full for a long, long time. - has a great, easy to hookup fast connector for the heater. Face your heater, open the tank compartment on your left, and look for the 4" shiny connector dropping down from the top behind the in-built regulator hookup for the small 1lb tank. That's where you connect. - using this, you spare your internal connectors and regulators for when you go mobile. Eventually, regulators get used, gummy, or go bad. If you use this hose, your internal regulators last longer. - when you shut off the propane from the tank, the heater dies out very quickly. I understand that with the high-pressure hose, it takes a while for the propane in the hose to burn off. CONS: - costs more than high-pressure hose. Seems like a lot of cash for a hose. - the regulator may eventually gum up. Mine has. I used it every workday in my home office for 14 months (that's a lot), and now found my heater was cutting out when on the highest setting. So I bought a new hose like this, and instantly my heater is working 100% again. But instead of gumming up my internal regulators (and ruining the whole heater) I wore out the cheaper hose.
