Work well and water feels "smoother" than the hard water out the tap. I recommend potential buyers purchase two accessories. 1) the rolling base which makes it easy to pull the unit out from under the upper kitchen cabinet or back of the wall to refill the reservoir. 2) an extra pitcher to fill and place in the refrigerator for cold water and a continuous supply of filtered water. I m surprised at how much water two people can drink each day
It leaks from. Different points no matter what I do, even for one person I feel it's not big enough for drinking even 1 gallon a day. The cartridges are expensive.
If it wasn't for paying a chunk for shipping I'd return it. I should have got a water machine.
Very clean crisp water, the only downside Is the water container for the tap water gets stuck and is hard to pull out, I believe its from water getting stuck. But I’m happy overall a great solution.
