Product review (4 stars): buy the ultra model instead
I didn't realize when I bought it, but there are two choices for these filters- this one, and the "ultra" filter. The "ultra" is longer and filters faster. Apparently that's what my fridge had on it originally, and when I switched to the non-ultra, the flow was noticeably slower.

My recommendation is to spend the extra money on the ultra filter since these things already flow slow enough.

I still give four stars because it still works and still does a great job at removing the tastes from my city water
