Product review (5 stars): Fantastic Item for the price
Read alot of people's questions on this unit.  Figured I try to cover them mostly in this review.

Great kegerator.  Noisey so don't be surprised.  Fits two 1/6 commercial kegs.  Also fits two 5 gal Cornelius kegs.  The kegs have to be set in diagonally to both fit.  The 5 lb CO_2 tank can fit inside with the two kegs but it's a very tight fit.  The door will close but you notice a keg hanging out by a 1/4 of an inch.  Door is concave so it shuts.
It does not chill the beer to what most people are looking for but you can adjust the sensor.  I accidentally turned mine into a freezer.  Be careful messing with the sensor calibration nut.
My personal setup is two corny ball lock kegs with 1/4" MFL quick disconnects in the lines to switch the Sankey D couplers to ball lock couplers.  Local brew stores have other options such as angled Sankey D to ball lock adapters.  Straight adapters will not fit for commercial kegs.
