Product review (4 stars): Less expensive but still great quality
In searching for a water filter for my Samsung refrigerator, I found the Waterdrop on Amazon.  First stop was the review section and overall, they were good so I ordered one to try it out.  The filter was packaged well and came with a spare O-ring in case it was needed.  The filter was super easy to replace and I have had no leaks or other issues.  I would highly recommend this filter and it's much less expensive than the brand name replacement filter called out in the manual.  Recommend the three pack to save even more!
