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

Well the instructions were entirely in Chinese and this is a very dangerous device because you can overfill the containers. I'm sure someone will lose a limb or worse if it hasn't already happened. However, use a digital kitchen scale to avoid overfilling and refrigerate the container to preserve fuel as others have suggested. You'll never have to carry two cans of fuel again or spend money buying fuel when you already have around 8 cans that are half full or halfway empty. Get one now before legal troubles take it off the market. great product, really. Works well, just don't be an idiot using it if you like your hands.
