Product review (5 stars): Great product and great price, but shipping is slow!
Great product and great price!
Filters work great so far!  Have only had them for about 2 days so we shall see how long lasting they are.  The great surprise was each box had a coupon in it for the Protec cleaning cartridges, so I can go to the store and buy those now too!  Bad thing was that the shipping takes a long time.
