Product review (3 stars): Not plug and play
At least it was not for me.  I bought this Dec 2012, and it had the dual regulator, but it was bad.  I found that out the hard way.  Since it would not reduce the pressure at all (which is what regulators are  supposed to do), I shocked a new keg of high end beer with probably close to 100lbs of co2 instantly.  I know this b/c the relief valve popped/sputtered (they do this at about 100 or 115).  First I figured maybe it was a bad relief valve (replaced for $8).  Then after a lot of tinkering w/the regulator (I am handy), determined it was not reparable, and bought a new dual one ($60).  I will leave out all the stuff in between where I frittered away $40 on pipe nipples and a Kobnalt air toold regulator, to try and make the best of the bad regulator I was provided.

I'd been getting foam for a week, probably due to the shock in pressure, but this died down, esp after lots of experimenting with pressure.

I started getting serious about temp (it was at about 42 F at its coldest - not cold enough for me, and probably adding to the foam problem, maybe).  Disassembled the t-stat, modified the factory screw setting, took readings for couple days, found a nice cold 35, yay!

Next started experimenting w/replacing line, b/c there was still foam, did some reading on my brew websites about line length and system balancing to reduce foaming.  Had some trouble getting the lock nut off the spout assbly that fits in the tower, inadvertantly damaged an o-ring, let air seep in by the spout for couple weeks (more foam) until I figured that out (what clued me in was the liquid draining back a little in the line).  They were nice to include a spare parts bag full of o-rings.  Grinded the sides of the wrench they provided to be able to fit in the tower to secure the nut again, more carefully this time.  Anyway it was too weak to lock down the co2 nut, so pipe wrench worked better for that, and didn't mind grinding this tool down, put it to good use.

I am a "project" guy and love to tinker, very forgiving, and esp do not send things back to warranty never never land.  I enjoy what I learn, and education is expensive, and in the end I am about there (3 weeks later).  I enjoy this a lot, but if you are not like me, then think twice.  If you are into modifying your stuff, you'll love this hobby/project.

I am still giving this 3 stars, b/c I love what I get out of it (now).  But it's cost me time and money to get there.  I'd probably do it all again.
