I ended up getting the G-WORKS Gas Saver Plus and a few of the small canisters. After using more than half of a small canister ‘s fuel I gave the
G-WORKS Gas Saver Plus a spin and it worked quickly and flawlessly. Even the little air-bleed button worked smoothly and did its job. A scale was kept close so as not to overfill. Yesterday it only got up to 70° so a hot mug of tea to go with gourmet chocolate, berries and nuts was sublimely life saving and luxurious.

The G-WORKS device is very well made with some serious craftsmanship.

I always shake my canisters to make sure the iso is well blended with the pro. I can see the draw to less expensive butane over isobutane or the isopro blend but I’m only interested in isopro even with warmer temps here. It’s the cold mornings when we fire up the mobile hearth.
