Product review (4 stars): Why spend more?
I was a bit skeptical about using 3rd party / off-brand water filters for my brand new -- and very expensive Samsung french door refrigerator -- but this filter plugged in, hassle free, no leaks. Tested with a TDS (Total Dissolved Solids) meter and the readings are showing close to zero. I had previously tried a Homedepot HDX brand water filter and that initially leaked. No issues with the WLF-20B, though!
