Product review (4 stars): Very pleased so far
We have a Samsung French door refrigerator and have always used the Samsung filter.  The last one we bought was a nightmare to get in.  After checking online, we discovered this is a common problem and you have to modify them to get them to work.  My husband took it to the garage and did some shaving away of the teeth to make it work.  I decided to try this one and expected the same hassle but at least it would be a lot less expensive.  Imagine our surprise when it went right in and locked with no effort.  We have only had it in for a week so I can't attest to the longevity or effectiveness yet.  I also am not sure it filters same sediments as the Samsung one although it does say comparable.  I also like the fact that it is made in the USA.
