J. Sollien: Works great, but read the directions carefully

This heater is great once you learn how to use it. It's not as easy as just turn a knob, there's a process to it. However, once you learn it it works great. We have a 25lb propane tank hooked up to it with the hose kit accessory. If you're going this route, ensure you release the gas out of the gas line before turning it off. Otherwise the seals will wear out and it won't last very long. You can do this by simply turning off the gas propane tank FIRST and letting the heater burn off the gas until it goes out. Then rotate it to the off position and it's good to go. The kit hooks up perfectly and easily inside the unit where the small green cylinders usually go.
