Product review (2 stars): Regulator doesn't work/Warm beer
The regulator/gauges that come with it absolutely do not work at all.  The default setting allowed for so much pressure to come off of the CO2 tank once I opened it, it shot out of the relief valve and would not stop. Once I turned down the red knob on the front, it sent CO2 to the keg without losing any.  However, the gauges still do not work correctly.  When it's all the way off, it reads "20 pounds".  So I never truly know how much pressure is being applied.  I'm not sure how much CO2/beer was wasted from having to GUESS where the gauges were at as I tweaked it.  I had to order another regulator off of a keg website at a substantial cost that eliminated the "savings" I thought I was getting by purchasing this.  Also, the beer isn't room temperature by any means but it could be a lot, lot colder.  It's certainly not bar quality.

It's better than not having a kegerator I suppose but I'm not thrilled with the performance so far.
