Product review (5 stars): Easy Choice
My second time to order the Water Sentinel WSC-1 filter, because my 1st time use with this filter was positive.  Although the filter's maker recommends replacing every 6 months, there was over a year of regular use before taste-noticing it needed replacing.  Easy to install, no leaks, works great, best price.  I noticed the water sealing gasket (where it contacts the fridge with the twist/lock connector ) was moved from the outside diameter to the inside part where the fridge's water nozzle plugs into. Works fine and a better design in my opinion.  Comes with a handy "Water Replacement" decal to place on the filter.  States on the filter "Made in USA" which is a plus to me.  This new one has been working perfectly now for several weeks.
