Bests & Worsts Reviews from Amazon

Works 100%. You have to pay attention to tank temps. The warmer tank will always fill the colder tank. If you’re 20lb tank is colder than your 1lb propane tank.....you’ll empty out the 1lb back in to the 20lb Freeze your 1lb for 30minutes. Make sure it’s colder than the 20lb tank. It’ll fill beyond 1lb if you want. The tanks can take 20% overfill. Takes 1 minute to fill a 1lb tank not including the chill time
