Product review (4 stars): Good starter chiller
For the price, this was a decent buy.  As other reviewers mentioned, the temperatures do fluctuate a little and it's definitely a lot colder on the bottom than on the top (+/- 5 degrees).  I have to set mine to 53 degrees to get it to 55 degrees on the bottom, while the top would be around 59 or 60 degrees.  It can only hold slender cab bottles 4 across.  If you want to still have 4 across with 1 pinot bottle, the pinot bottle has to be put in neck first.  Good starter chiller.  Would probably want something better next time, but this still does the job.
