Review on G-WORKS Gas Saver Plus with Lindal Valve Canister Shifter, Refill Adapter, and Air Vent Function by Jacob Mayberry

G-works works well. It's just a female-to-female Lindal valve connection with a stopcock and bypass valve to vent the gas from the receiver bottle. Easy. But it's beautifully made and works a treat. The advantage of this is that instead of filling up with full canisters, you fill up almost empty and then empty canisters one after the other with the fuel required for a specific journey. Only take what you need. Combined with an adapter or two (and the intelligence, knowledge, and attention to detail) it's easy to refill Isopro cans from multiple sources to create your own mixes while saving money. I recommend, even if you're only filling with butane (like me), keeping a log and using an accurate scale to know how much fuel is in the can and how it shows up with use. At least it helps avoid overflow.
