I like how easy the unit is to install. Fits directly onto earlier filter adapters, will not run or drip. Best of all, the filter turns off automatically when you turn off the tap. The bad news is the cartridges should last for 200 gallons, or let's say two months with typical home use. But now I'm on a second cartridge, ordered separately, and they only last three weeks before the flow drops to a slow trickle. I doubt I even had 50 gallons. from these cartridges. They either need to revise their description or come with a higher capacity cartridge. Every three weeks would be too expensive.
