Product review (1 stars): Does not work!!!
Tier1 Frigidaire WF3CB PureSource3 Comparable Refrigerator Water Filter would click in place after MANY tries.  Popout immediatedly after first use and will not stay in again.  I have to return to vendor DiscountFilterStore.  DiscountFilterStore agreed to take back the defective item but I have to pay for the return postage.  I will not buy this filter and will not buy filter from DiscountFilterStore.
