Product review (1 stars): junk
I purchased 2 of these Wf3sb filters 5/2011 from amazon ltd for the new refrigerator I bought from sears.  I wanted to make sure I had a set of filters when they needed to be changed. I just replaced the original filter today with the new amazon filter and it did not work.  I purged the water and got about 1 gallon out before it ran out of water pressure.  I put the original one in and it stilled worked so I know it is a bad filter.  The second filter was then installed, the same way as the other two. After purging the water, the pressure is very weak but much better then the first original filter. Humm $60 worth of filters purchased from Amazon and neither will give me water pressure, I think the filters are bad. The original one lasted 7 months. It also is very odd you cant contact anyone here on amazon for a return or even for customer support. Pissed off in Wisconsin!
