This honestly is amazing, and I wish I knew about vapor distillers like this sooner. The water tastes just like bottled water. I saw complaints about the heat, but it's honestly not an issue at all (barely warm to the touch even after running for a few hours, and the heat to surrounding surfaces is very minimal). Perhaps this is a newer model, but I have other appliances that get a lot warmer (like the slow cooker and instant pot).A gallon of water (4 liters) is a lot, and the fact it only takes a little over 3 hours is amazing. We set a timer on our phone for only 3:20 min to ensure it doesn't boil down to nothing (easier to clean that way). My only complaint is having to unplug everything to clean it, but it's only a very minor hassle. A little bit of white vinegar mixed with water can be used to get any residue mineral deposits off (just let it soak for an hour, and can also do a cycle to clean the upper part too).Overall, it was well worth the cost (pays for itself within a couple of weeks). Would highly recommend this version in particular (with the glass pot - it's really thick glass).
