Well made and works. Just bought a second one to give a friend. I used mine for months now. I fill 1lb propane tanks daily using this. No complaints.
This thing is awesome! I've filled up 2 cans from my standard BBQ sized tank.. much cheaper to refill and convenient.
Just to give ull a heads up u have to put the empty tank in the freezer for 25 mins then it will fill the take up. I did it and fill 4 tanks and it fill them to the same weight as a new one.
Best thing I bought for my camping equipment in years and it paid for itself in about two weeks. I love it! I even sent my friends on scavenging missions at RV parks to find empty 1lb tanks to refill and I now have two milk crates full of them "Just in case!".
Solid, well built device that seals well and performs flawlessly. I place my small empty cylinders in the freezer for about 30 minutes before refilling. Remove small chilled cylinder from deep freeze, screw the fitting to small cylinder, then attach to my 20 lb. Cylinder, which I have inverted, and then open the valve on the 20 lb. Cylinder slowly. In just a couple of minutes, I have a perfectly filled, full small cylinder ready for use. Works like a charm!
