Product review (1 stars): Doesn't work like old fast fill
Replaced a PUR fast fill with this filter and water barely comes out, as well as very little ice being made.  Called whirlpool and they suggested I return the filters to Amazon, maybe it was a defective filter, Amazon was great about exchanging the filters, but the results were the same.  Called to trouble shoot with Whirlpool and they suggested a service call.  Well 98.00 later the "certified Whirlpool technician" said it's the filter.
