I ran as much water through it as recommended after installation. It's been in for a week and the water still tastes bad - including a strong chlorine taste. Surprisingly, the ice isn't that bad.
I remember the original filter took quite a while to start giving good tasting water - maybe there's something different about this refrigerator.
No problems with installation or fit, and the water flow is strong. I'll update if the taste suddenly improves, but I can't keep using mainly bottled water for much longer.
