Product review (1 stars): Slow flow, bro.
I have one overwhelming problem with this filter: the water flow rate is significantly slower. We use our filter a lot so this becomes a daily annoyance. I also believe that the flow rates are inconsistent from one WSS-2 to the next because we bought a three pack and it seemed like one was ok (still not great), but the other ones were dog-slow.

When filling an 8-cup measure for cooking, the water flow usually clicks off once (a timer clicks it off to prevent flooding) with a Samsung filter.  With the WSS-2, it clicks off three times.  The flow rate seems to be about 1/3 the speed/volume.  I don't have time for this.

To be fair, we've never had the problem of noisy rattling with a WSS-2, and the flavor seems to be comparable to the Samsung. However, we are NEVER buying this again. In this instance, it appears that you get what you pay for.
