Product review (3 stars): Does what you'd expect
Inherited a new fridge with our new home, and water and ice ran notoriously slow. Replaced the filter with this and things are running and tasting great!

Edit: downgrading from 5 to 3 stars based on the full-life experience. My fridge says to replace filters every 6 months. I feel like these give you 3 months at best. The price is still pretty good for what you get, but be aware you'll be replacing more often. While it works, it seems to work well, but I've gone back to the original manufacturer's filter for this.
