Product review (4 stars): A good value, seems to be a competent replacement, takes too long to flush
This is my first replacement filter for my fridge.  At this point it is hard to say if I'll be satisfied, but it looks like this is a good choice so far.  I ding it a star for not including enough information and taking way too long to clear.  I give it 4 stars because it seems to work as well as the original and it is 2/3 the price.

I seem to remember the stock filter taking longer to fully clear than 5 minutes but I didn't time it.  This time I timed it (easy, because the fridge shuts off the flow after 1 minute).  It took 18 minutes to fully clear (I'm glad I turned off ice maker before I put it in).  Even after 15 minutes there were more tiny floating bits than tap water, and the taste was off.  I wouldn't describe it as plastic, but otherwise it sounds like what other reviewers noticed.

As far as other concerns brought up in other reviews:
- No leaks, no drips.  The flow is about the same as the stock filter; 15 seconds for 1 pint.
- The filter is a little bit taller (and slightly heavier) than the stock filter, but fit the space for it without issue.
- The threads and how it fit were absolutely no problem.
- There is a sticker in the box I got for when to change the filter (I hadn't noticed before I took one from the Samsung box).

There was a tiny tube of what I believe is silicone grease, there may be enough for the next filter, which will be the Samsung stock replacement I got at the same time.  I'll try to remember to followup but it will be about 3 years, based on our usage and its gallon rating.

We use about 26 cups of water per week (mostly for coffee, some ice) which means this 300 gallon filter should last about 3 1/2 years.  I don't see any reason to change it early, so I'll add 2015 after the July sticker with a Sharpie; this will give us about 2 gallons per week so I have a margin.

Our usage may be lighter than some folks, we like to filter out the minerals from tap water that would get in the coffee maker, and of course our ice comes through the filter, but we cook with tap water.  Check your own usage, don't use my numbers!

My fridge has a light that comes on to indicate it is time to change the filter, but it comes several times before it is really time to change it.  I don't know how they determine when to light the light, so I ignore it and go by the date on the filter.

Good news, my wife looked at what it filtered and figured out that the stock filter does not filter out fluoride, this one should be the same as they both are described as blocks of carbon.
