I got this product back in 2012, and now in 2014 is working great! BUT, when I first got it, it leaked a lot. Had to submerge the whole unit, take it apart, and reassemble some pieces with teflon tape. I overtightened one piece and cracked one of the T's. I also wouldn't put a lot of faith in the check valves. I don't know how much pressure it takes to push back through one, but I have inadvertently pushed beer through the manifold. It probably slowed the rate down a bit, but it was still a huge cross contaminated mess. I've also noticed certain valves are at a very annoying resonance frequency with the gas, making an incredibly loud whine when first connecting a keg or force carbonating.That being said, it works good, and is very easy to see which lines are on or off. It also looks quite awesome in my Keezer!
