I always thought it was insane that the small tanks are throw-aways, from cost as well as environmental reasons. Being able to safely refill them is a win-win :-). Pretty easy for the first time, though I don't think I filled them all the way and will weigh them before and after next time. Just carefully follow the directions about safety and freezing the disposable tanks overnight. I would probably tighten the adapter fitting to the 5 gallon tank with a Crescent wrench first, as the disposable tank wants to unscrew it when you tighten them on due to the lefty-righty thread mismatch between the two tanks.

High Quality Refill Adapter

This refill adapter is a high quality product of solid construction. The sellers description was right on the mark and I got my product two days after ordering. I have accumulated many 1lb propane tanks over the last two years and rather than discard them I decided to refill and reuse them. This adapter should provide me with many years of excellent service. DozyAnt certainly lived up to their promise.

disposable propane cylinders no more! This thing makes all devices that use propane so much more useful, economical and better.

I love this thing! So easy to use and now I use my weed dragon with attached propane cylinder almost daily. I have a full 5 gallon propane tank in the shed that I use to fill tanks on a regular basis now. The steps for me are very simple. 1. put empty or almost empty tank that you wish to fill in the freezer for 30 minutes or more. 2. attach the DozyAnt to your cylinder anti-clockwise. Tighten with wrench. 3. thread frozen empty propane bottle onto dozyant 4. turn main propane bottle upside down and open the valve all the way. 5. stop it immediately after you hear the sound of rushing water (propane) turn to a "ting" "ting" "ting" sound. 6. connect propane cylinder to anything and bleed off some propane as it will probably be a little be over filled. Don't just put it away. I use my weed dragon and it goes on turbo pressure for 5 seconds or so and returns to a normal operating pressure. 7. weight the entire filled tank and compare to a filled one if you want to be extra safe. And presto, you just filled a 5 to 10 dollar tank for around a buck. I love this thing!

Works just fine!

I tried this out right after I got it, and it works just fine. The machining quality seems to be good. I used the freeze-the-cylinder-first method and got about 12 ounces of propane in. One warning concerning method- don't do this: I thought I'd be clever and freeze the cylinder again after getting 12 ounces in, and fill it again to see how much more I could get in. Don't do that. It is very possible to very easily put way too much propane in. You can't fill the cylinder to the very top- propane cylinder need some 'headspace' of just gas at the top to let the propane expand when it warms up. I overfilled mine by several ounces, and I'm sure it would have popped the safety valve and dumped propane into my garage if I'd just let it warm up on its own. I stuck it in my buddy heater right away and let it burn off the extra propane while it was still cold. It was a pain, so don't do that. Overall- very satisfied, but pay attention to how you use it. Weigh your cylinders before and after, or you risk an accidental propane release and potential fire/explosion.

Solid and well machined, does what it's supposed to do.

Well-machined. Just filled 4 bottles with no problems. Weighed them afterwards, only one was filled more than the factory fill (about 100 grams more than factory fill). I bled that one down to closer to factory fill weight to avoid any potential problems. If you do use a rod to depress the main fill valve, make sure it is non-sparking aluminum or brass, and of course far away from any potential ignition source. I use a two-fold fill method. First open the supply tank for one minute, which will fill the tank half to 2/3's full. Then using my non-sparking rod, bleed the tank you just filled for five to ten seconds. The bottle will become very cold. I slip an insulating sleeve I made from cardboard and bubble wrap over the bottle, then quickly as possible thread it back onto the supply tank and then open the supply tank again for a minute. Bottle will fill to one pound rated capacity.

This product is a really great idea. Being able to refill the small one pound cylinders with this is absolutely amazing. I like the fact that it's got the safety so I don't over pressure the cylinder.

Worth it.

Totally worth it if you're trying to save money on propane refills. Watch all the youtube vids out there concerning refilling the 1lb propane bottles. Do it outside. Make sure you arrest all sparks and flames beforehand. There is a video that claimed you could do it without freezing the bottles. You can try it. But I seemed to get closer to full when the bottles were chilled. Depending on how much propane you use, this adapter should pay for itself over the course of a single summer, if not sooner than that. I'd say go for it.

1# tanks have a pull schrader style valve

I got a pair of small needle nose pliers from Iowes, they are the blue house brand and don't have any gripper teeth on the jaws but they are short enough to get in between the tanks and pull the end of the schrader valve out by using two hands.. carefully. I put the valve on the 1# cylinder at around 3 o'clock when it's upside down ready to fill. When it stops making noise from the liquid filling the 1# then I get the pliers in there and using two hands (one to squeeze and one to push the pliers back as I can't get in there to pull away) and pull and hold until you get some mist of propane liquid coming out. Let it fill up the rest and shut the 20# valve off and disconnect. You will get a full tank as relieving the head pressure (as the 1# fills, the vapor gets compressed because of the liquid flowing in and once it's pressurized enough then more liquid can't come in, thus releasing that vapor and thus pressure, it allows the liquid propane to fill the 1# tank). Just watch out because when the liquid boils off it will freeze your fingers quickly..

Works and should last forever.

This item works well when the big tank is warmer than your smaller receiving tank. Just put the small canister in the freezer for a few minutes and it should be good to go. Heads up, those small canisters can get cross-threaded easy so probably could reuse them a few times before the threads are done for. A great way to recycle and reuse something I would consider to be a durable product. It's a shame that those small canisters are considered by some to be a single-use product.

The threads screw in and out smoothly and creates a great seal. It causes the propane to flow at a comfortable rate which gives the tell tale sound that you can start working the relief valve to let more in. It allows me to be very accurate at bringing my canisters back to factory levels every time without purging and wasting any.
