We got this last week. Took a bit to assemble but once done, we filled it with soapy water, turned it on, and it did exactly what it claimed to do. It produced almost 1 gal of distilled water in about 3.5 hours. We dumped that out, rinsed the distiller and glass pot, refilled it and turned it back on. Again, we produced about 4 L in 3.5 hrs. We have mixed that distilled water with the filtered water we previously generated in a pitcher, to produce a 50:50 mix of filtered tap water and distilled water. So far, the result tastes great and is much healthier. The unit turns off when empty, turns on with a simple push of a button, is easy to dissemble for cleaning/rinsing, is easy to fill, and generates the distilled water we want. It has been working perfectly for about a week now. So far, so good! If it breaks or malfunctions in the future, I will edit this post to say so.
