Works well.
It works very well. I use it to supplement our water, because we use 2 gallons a day and its a hassle to use it that often. It does accumulate buildup even tho we try to turn it off before it runs dry. It also heats up the kitchen. In the winter that's fine but in southern New Mexico in summer, no thanks. But it serves its purpose, which is to provide clean, safe water when we can't get out to fill our containers with reverse osmosis. The directions confused my elderly mother, but I was able to get it going easily enough.
