Product review (5 stars): Sometimes, the cheaper alternatives do work!
Waterdrop has done it!  I am happy that I spent extra time looking for a good, less expensive alternative to a brand-name filter. After all, for a price conscientious consumer, such a significant difference in price is a good reason to begin looking for options. I see no difference in performance whatsoever when compared to the more expensive brand-name counterpart. The water is clean and it does not smell of chlorine. The filter fits and works well with my refrigerator. It also comes with a set of stickers, marked for each month of the year, so you can attach it to the filter, as a reminder to yourself for when it needs to be replaced (unless you refrigerator tells you first).

Considering the price and the quality of this filter, it would be unwise of me to recommend any other brand / option.
