Product review (3 stars): Nice product.  NOT FOR SAMSUNG
This appeared to be a nicely made product.  However, it does not work in a Samsung fridge.  While it is very close in design, it was off just enough to leak a little without our noticing for a couple weeks.  About three weeks in, we opened the fridge door, we noticed some wetness under the filter.  When we went to wipe it up, we bumped the filter and it shot out of the opening.  I purchased a Samsung replacement (for a lot more money) and replaced this unit with a factory one.  No more leaks.  Wish these fit.  $18 compared to $45.......
