Product review (1 stars): Wrong item received TWICE!
I received the international type of water filter mistakenly, and I exchanged it through Amazon.  The replacement went very smoothly, and I received it quickly.  However, the second filter received was also the international type and the wrong item.  In frustration I called Amazon, and they gave me a refund and a $10 credit on a future purchase.  They told me not to buy this item again, and they would investigate what was happening.  I would have given zero stars if I could.  However, the seller did ship the items quickly.
