Product review (2 stars): lasted less than 6 months.
Bought this bad boy back in April of 2013.  August of 2013, it crapped out again.  Granted, this may point to some other problem, but really.. it's input from the house current, routing via wires and then distribution by this unit.  Not a lot to go wrong with house current and wires, since those remain pretty constant.  My vote goes for this guy.  Only 20 bucks, true, but still...  6 months?  A 20 dollar pocket watch lasts longer.
