Product review (5 stars): Great Value
For the money, it's hard to imagine being disappointed with this kegerator.  Easy to put together, with the exception of the tower.  My unit gets plenty cold without having to tinker with the thermostat.  I find it to be quiet, although its in a room we don't spend a lot of time in.  My only issue has been with co2 pressure, but that's my own fault.  I've had slight problems with flat beer and lots of head, most likely from over pressurizing the keg.

Pros -

Great price
Easy to assemble
Quiet
Cold
Caster option

Cons -

Tower is tricky to get sturdy
2.5 CO2 tank (I already had a 5 tank, thankfully)
