Product review (5 stars): Causes water line to freeze
Giving it 5 stars so everyone will see this.  Every since I placed this into my fridge the water line stays frozen. I've thawed it out and in less than 18 hours it is frozen again! Ice repeated this over and over again.
I've never had this problem with other water filters.  So I went out to Wal-Mart, bought another filter, thawed the water line again, placed the new filter,  and guess what? No more problems! No more frozen water line
