Product review (5 stars): LOVE IT
We've been using this at work for a little more than 7 months.  It has worked flawlessly.  Since then, my wife bought another brand, "igloo", for home.  Despite the igloo being much cheaper, we wish we would have sprung for another one of these.

HIGHLY recommended.

Update, 8/1/2016: It finally died.  After ~ 2.5 years, it no longer works.  We'll probably buy a new one.
