I purchased this item recently and it is not worth the money! The first one cracked and the second one smells like nasty rotten fish.
I'm returning it right away and going back to my britta ! I thought it was the cup so I tried another one. I threw away my existing water bottle thinking it was the problem. I even cleaned out my refrigerator today.
The culprit is the nasty zero water filter. I tested the water today as well and it looked normal.
Taking it apart was so smelly. It's a good thing that I kept the box.
