LIXADA Gas Saver Plus, Gas Convertor Shifter, Refill Flat Tank, Conversion Adapter, Camping Gas Adaptor Valve, for Nozzle Bottle Type/Butane Gas Cartridge/Lindal Valve Canister

I watched a lot of videos on how refill my own bottles. This tool worked great and will save me a lot of money.

Waste of money.

I've used it about 5 times to consolidate and transfer fuel between MSR Isopro fuel canisters. Much cheaper for me to buy the 16oz canisters and then transfer to a 4 or 8 oz canister that is empty or only partially full.How I use it: Weigh the canister you want to add fuel to, which will tell you how much is currently in there, with a postage scale. Put canister you want to take fuel from outside in the sun (if it's a warm sunny day). Put canister you want to receive fuel into the freezer. Wait 15 to 20 minutes. Collect both canisters. With valve in the off position, screw both canisters into the appropriate side of the transfer valve, making sure that the threads of the canister you are currently screwing in are facing up (otherwise you will get fuel spraying out if the threads face down while you're screwing in). Once both canisters are screwed onto the transfer valve, open the valve and allow fuel to transfer. Once transfer sounds complete, unscrew the receiving canister (with threads facing up) and re-weigh it to verify you added the amount of fuel you were trying to add. Repeat sun/freezer steps and transfer again if necessary.

The device works as described, but no matter what I do there is still 5-10 grams of fuel left in the can I am emptying . I put the receiver in the freezer for an hour, the donor in the sun or on a heat vent for the same time, yet some fuel will not exit the donor when they are connected. Still, it is much better than it was, and I could carry several nearly empty cans on a one night trip where weight is less of an issue. Overall I recommend this product.

Let ‘er rip with this little gadget! Works great.
