Product review (5 stars): So far so good
Ordered the Samsung version previously, it was easy to install and worked well.  I decided to try the Water Sentinel brand because of the cost.  It was easy to install, the only visible difference is that it is slightly smaller in diameter.  It made a little noise for the first couple of hours, but 4 days in there is no noise at all.  The water/ice taste fine.  I hope it lasts the 6+ months the Samsung did; I won't know that for several months.  However based on my experience today I would recommend this item.
