The biggest downside for me is how much water it wastes, and the filtration process is also quite slow. I honestly wish I had known this beforehand because I probably would have gone with an under-sink option instead.
That said, the taste of the water is excellent. I have no complaints about the water quality or taste.
It works, but the advertisement did not mention the tap water tank is used to collect contaminants, must empty every cycle (can’t add water to tank), is difficult to align, requires pressure to re-sit, and you cannot add water to an empty tank. It’s easier to empty the tank, replace it on the unit and add water with a pitcher, but it doesn’t work. I do not regret the purchase, yet. I’m hoping the seals on the tank will hold up for at least a year.
This has been working really well for me! Very happy with the purchase. The tank doesn’t fit perfectly all the time, but still totally functional. It does produce a significant amount of waste water. I dump it in the tank of the toilet after flushing so that I’m not wasting all that water.
