I've been using it for a couple months. It works well. Pretty much just fill it and hit the button to get distilled water. I don't use it for any other fluids. Using vinegar to clean periodically helps with limescale. I fill it with1c vinegar and the rest with water and let it sit overnight. Lime comes off easy. The carbon filter was a trick to figure out since the directions illustrations are impossible to understand, lol. You just got to wiggle the nozzle and tilt it. I can't explain it very well, but eventually it comes loose and you can slip a carbon pod in. I soak mine and rinse it well before putting it in the distiller. The flavor is a bit burned if that makes any sense for water. Kind of like a heater smells. Might be the carbon. Might just be the fact that it boils the water into vapor. I don't know. It's tolerable by itself but I mostly use it for tea and coffee machines. No more limescale in my machines! I just wish they sold the bottle separately so I could buy multiple for storing.
