Bought two filters thinking the first was defective. Nope. Both do not get a good seal in my fridge. The original filter worked no problem. After a bit of troubleshooting on the web, I noticed folks will shove a wad of paper towel to get the filter in the correct position. You heard that right, an expensive filter requires the user to jam the filter just right in order for it to function. Unbelievable. [This review was collected as part of a promotion.]
