Product review (1 stars): What's the worst that could happen
I thought I'd give these a try despite the negative reviews, since they were specifically listed as a replacement part for my Thermador refrigerator unit. With these filters being a fraction of the cost, I figured I'd try them out and if they didn't work, we'd just send them back to Amazon.  What's the worst that could happen? Well, I discovered the worst thing that could happen when the filter didn't initially work and so I left it in the unit to charge, then it flooded my kitchen floor overnight.  Don't take the chance on these, and if you do, keep a close eye on them for the first 8 hours.
