Revised......This item only worked for a week.  I haven't had a chance to investigate the malfunction.  If it turns out that the malfunction is not the cause of this item, I will recant.

I was compelled to come back and edit my previous review.  The malfunction was not the fault of the pump.  The pump actually works great.  My apologies.
