It's already saved us $$ since we are no longer buying bottled water, and I am so glad to reduce our use of single-use plastics as well. The water tastes great and the system works like a dream VANESSA Been through many different systems from Lowes (AO Smith) and Home Depot. Waterdrop filters are my favorite in design. It obviously works like it's supposed to. But the ease of changing filters is awesome. It's a breeze now. Love the design. Kenny Roberts Great system. Was buying bottled water before but even some bottled water tasted off. I don't have that issue with the waterdrop RO. Water tastes great. Shellene TURNIPSEED After many years of unsuccessfully trying water pitchers and refrigerator filters the Waterdrop 800 with UV sterilizer has finally cut off my dependence on bottled water.
