I bought one for an early Father's Day gift to myself last time it was posted on Woot. So far I'm extremely happy. The growler jug concept did not work well for me unless I had a gathering of other craft beer lovers because once a growler is opened the beer quickly goes flat. With the ManCan I can fill it with my favorite high gravity draft from my local brewpub, and then dispense as much or as little as I want, and the beer stays fresh in the meantime. I filled it 10 days ago with a Belgian trippel, and tapped about 6 oz last night for dinner. Delicious. The CO2 cartridge works well in keeping the beer carbonized. The components seem to be of high quality.
