We got this five months ago. 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 over1 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 of pure distilled water 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 five months now. So far, so good! No leaks or malfunctions. If it breaks or malfunctions in the future, I will edit this post to say so. Some people have complained it leaks. It does not. Rather, to pour the water, you have to position the distiller directly over the big opening above the pitcher or glass you pour it into. It may drip a bit as you pour, but so what. The pitcher or glass should catch all the water.
