Product review (1 stars): A Good Upgrade, but Could be Better
I got this for a Nostalgia Electric single tap kegerator. It replaced a 2.5" tower after a little bit of work to the top of the kegerator with a drill and some rivet nuts. The quality of the hardware components is all pretty good, and I'll be sure to test it out real well during the Super Bowl. I do have a few complaints with the kit, two of which were fairly easy to fix. The Y fitting on the regulator and the two shut off valves in it were fairly loose. An adjustable wrench fixed it up. The one valve was so loose that I was actually able to tighten it some by hand. The other issue is with the insulation in the tower, or lack there-of. It came with a piece of thin foam that looks more like it was packing foam wrap as it was an 1/8" thick at best. I removed it and replaced it with a piece of pipe insulation with an OD of ~2 5/8" that fit perfectly. The last complaint is that the beer lines are only 4-5' long, and the airlines are basically the same length. I didn't try to lengthen them yet, but will likely get some barbed couplings, clamps, and some more tubing later, but I will see how much the beer foams first.

2/12/2014 UPDATE: Used the system for the Super Bowl and had a few issues. The one side was not getting CO2, not sure if it was a regulator problem or something else. Found it a few days later when the line side pressure was 2 psi. Checked the connections and looked for problems, turned the pressure up and problem solved. A week later, my CO2 bottle is empty after maybe a full sixtel (likely less) of beer from the two kegs. Got my 2.5lb bottle filled and checked for leaks only to find everything at the "Y" fitting leaking. Both valves in going into the "Y" and the "Y" going into the regulator. I guess when I tightened them initially, it wasn't tight enough. The one valve I couldn't get to stop leaking, so I removed it and then all the teflon tape, then had to put more on, probably close to 10-15 wraps before it actually stopped making bubbles with soapy water. Checked other areas and didn't find anymore leaks, but time will tell if I actually got them all. Hopefully they're all fixed now as I'd like to not loose all my CO2 before the beer is gone. I'd rather give it 2.5 stars if possible after the latest issue, but I can't give/take a half star.

2/27/2014 UPDATE: Another update, and the rating on this kit has dropped to 1 star. The regulator that came with the unit is bad. On top of all the leaks from it, it just doesn't work. I could not get it to maintain a constant serving pressure. It would either get set at 8-10 psi, then a few hours later be at 30+ psi, or you couldn't get the pressure to go up at all. Sadly, it usually increased steadily, and there is now a mess in my kegerator as it forced beer out of the lines at the faucet when it was over pressurized, and the beer leaked down into and onto everything inside the kegerator. I contacted the seller, and the response was "we frequently have regulator issues, here are instructions to fix it yourself". Sadly, it took several tries for them to actually send the instructions. I don't see how you sell a product when you frequently have problems with the most critical piece in the product. Needless to say, after I finally got the instructions and took apart the regulator, there was nothing inside it causing a problem, so I put it back together, and would you imagine that it is still bad? Now I need to try and get a refund. Luckily, the regulator that came with the kegerator is fine, so I just swapped the Y fitting over onto it. If I could buy again, I'd go spend another $20-30 somewhere else and get a different kit from another vendor, as this one is not living up to any standard other than poor.
