Well I know this thread is several months in hibernation but I got 2 of these kegs/bottles & a tapping head coming this week. I’ve got several kegs but I think this will be good for taking beer camping and stuff so you’re not dragging a keg and big Co2 bottle around. For you guys that’s had them for a while how you feeling about them?
I've 'kegged' in them several times. They work and hold pressure well. I've encountered small air leaks where the caps screw onto the tapping head. Those can be a bit touchy, and I used plumbers tape when I couldn't manage to get an airtight seal just by screwing/unscrewing. I'm yet to have any liquid leak, but note, because of the tube and elbow joint, you have very limited abiltiy to screw/unscrew the liquid cap once it's assembled. So need to get that one right on the front end, or it's tricky to fix.
Also, I unintentionally wound up spunding a couple of beers in these that I thought were done fermenting, but the increasing pressure buildup (which is easily detectable by just feeling the sides each day) said otherwise. But it was never a problem because you can just feel the pressure build up and use the pressure release valve to vent a little bit as needed. These seem to hold pressure really well (as long as you check for leaks early - I had one beer that I discovered three days later had a leak, so most of the priming sugar was used up but no carbonation due to the leak. That was the only beer I've tried to carb with priming sugar in one of these. The rest were force carbed).
But I like them and will definitely keep using them for certain purposes (mostly friends home taps).
Also, the carrier handle can't fully extend on the front-side of the tapping head (cap-side). You need to swing it around the back when the tapping head is on. It has not happened to me, but I could see the extending handle putting too much pressure on the cap-side of a full keg and breaking the seal and/or cracking the plastic head. I don't think these things are durable enough to handle much rough or careless treatment when full.
