Great accessory makes refilling 1lb propane bottles simple and easy. But the refillable bottles with this and never look back.

Works great! Love it!

I've only used it once, to fill 3 Fuel Kegs, but it worked as advertised. I filled from a full 20 lb tank. It filled each of my three 1 lb Fuel Kegs in about 1 min and 17 sec. To get a sense for how much propane is lost from the vent valve (which is kept open during the fill, per instructions), I weighed my 20 lb tank before and after with a digital luggage scale (which I've found to be accurate in that it matched the airline scale). Filling 3 tanks used about 3.3 lbs from the 20 lb tank (so about 1.1 lb to fill a keg). Weighing the tank a 2nd time showed 3.2 lbs used (so the venting loss might be less than 0.1 lbs per Fuel Keg). I weighed my 3 Fuel Kegs before and after filling. They all weighed between 1.9 and 2 lbs empty. The first one I filled weighed 0.9 lbs more after filling (but I stopped filling within a couple seconds after the white mist appeared from the vent). The second and third kegs weighed exactly 1 lb heavier after filling (I filled them a bit longer, waiting for the mist to be more continuous before ending the fill). After removing the Fuel Kegs from the fill apparatus , I made sure each retained its plastic sleeve and o-ring (as other reviews have noted that these can get stuck to the filll nozzle). I also used a brass cap with rubber seal (purchased separately) instead of the pastic cap that comes with the fuel keg. I figure this is an added safe guard in case the Fuel Keg leaks. I tested one of the filled kegs in a "Big Buddy" heater. It fit just fine (allowing the heater door to close) and worked (on low, medium, and high). I got this setup for emergency prep, since I have several of the Buddy indoor-safe propane heaters (in case we can't run our furnace). So I likely won't be able to comment on how it holds up under frequent use, but I'm very satisfied for my purposes. The Fuel Keg seems sturdy and well-constructed.
