Has anybody used one of these from https://www.flipfuel.co/?
"What is FlipFuel?"
"Brought to you by backpackers to solve a simple problem. What do I do with this box of partial fuel containers I won't take on a trip? Now you can easily consolidate your backpacking fuel & recycle the empty fuel canisters. "
I must admit, I went ahead and purchased one anyway as they seem a great way to consolidate fuel, especially for this weight obsessed ageing backpacker!
