I ordered this to make my own distilled water and couldn't be happier. It works fairly quickly and I haven't had any problems over the first 3 batches, 2 water and 1 Dr. Pepper. The only minor complaint is that the glass carafe doesn't have a pour spout of any kind making it nearly impossible to actually use it as a serving vessel. I ended up pouring the distilled water into a fridge water dispenser with a spigot so you may want to pick up something of that sort if you don't already have one.
