Product review (4 stars): Quirky At First, Fine Now
I received this as a gift in December 2014 and have played with it for 6 months now. It works great once you figure it out, but the manufacturer should make this much easier. I use this for home brewed beer, and for local brewery beers where I can get the empty kegs filled. I do have the conversion kit to pressurize the kegs.

My initial impression was negative. I used three CO2 cartridges for the first keg. Obviously the system leaked CO2. I used a soap-water combination to find and fix a few leaks. In the process I cracked and replaced one plastic connector. It worked better after that, but still didn't hold pressure for more than a week. The manufacturer was no help, they basically told me that if I couldn't find the leak, they couldn't help me.

On the next keg, I blew through two cartridges in a day, and tore the entire thing apart out of sheer frustration.  In the process I discovered that the stem that penetrates the bung and connects to the tap head was actually threaded to the tap head. I unscrewed it from the tap head, and located another seal. That seal was not seated properly. I reseated it, threaded the stem to the tap head, tightened it all, and have been pouring beer ever since. I'm on my second keg with the same CO2 cartridge, so I think that I've solved my leaks.

My only complaint is that the manufacturers should show a complete diagram of the system, to include all of the seals. That way an owner could navigate the pressurization system intentionally to find leaks, instead of by blind luck like I did.  I'm now brewing more beer and kegging half of each batch.  The kegorator looks great, and works great now.
