I bought this 6 months ago and am still thrilled with it. The digital reader gives me great confidence with my filters. I change them every 4-6 weeks, but don't need to remember exactly when that was. I have been a zero-water user for years, but my old pitcher did not dispense water as smoothly. This one holds more and drains better without taking up more room. They have an excellent product. It may be overkill for my urban area, but even trace amounts of "acceptable" stuff in my water can build up over time. Zero water tastes noticeably better than tap.
