Product review (5 stars): Tastes great, less filling
Samsung is rated at 500 gallons or 6 months; this one is rated at 300 gallons or 6 months.  Go figure.
Price is about 40% less than Samsung (200 gallons less = 40% less so you get what you pay for).
I typically use this product for up to a year and taste is still pure, not even chlorine taste.
Previous reviewer who said it tastes like pee must have his water hooked up to his toilet.
