This distiller is slightly larger than many, but what attracted us was the on/off switch for AC power. No need to pull the plug to power down. It runs quietly, and was easy to clean up after use. We liked the plastic catch container - no glass to break! Our use is in a humidifier to avoid the white dust, and occasionally in an iron, etc. We do not use the carbon filter, which keeps things simpler, and particularly like the short flexible tube that can be attached to the spout to ensure all the condensate is directed into the catch container, and not dribbling off the edge of the lid with a slight misalignment. A tube of this kind could be added to similar distillers if they don't include one.We ran it on a Kill-A-Watt meter and were surprised to find that it consumed almost exactly the 900 watts at which it is rated, peaking briefly at about 905 watts, then settling down around 890-900 watts. It took about 3.7 kilowatt-hours to produce approximately 1.33 gallons of distilled water. (Note that we do not operate it at "full capacity", from fill line to dry - see next paragraph.)We avoid the overheating shutoff by measuring the capacity of the distiller just below the fill line (where we fill it), and note that level on the catch container. We power it off when the distilled water has filled to an inch or two below that. This leaves an inch or more of water in the bottom of the distiller. By not boiling it dry, we avoid depositing a lot of minerals in the bottom of the distiller stainless steel pot, and also avoid distilling over any small amount of heavy volatiles that boil at a higher temperature than water. We intend to plug it into timer switch capable of switching the 900 watt load, so allowing it to run without checking its progress. It is pretty reliable in timing, if started with the same amount of water, at the same temperature. We use hot water from the tap (actually just warm, as we keep the water heater set low), and our water is softened, which helps avoid lime scale. A cleaning with vinegar removes nearly all the "staining" we get in the bottom of the distiller pot, leaving only a faint stain that penetrated the surface of the steel right away, but is not really darkening with repeated use.Starting with hot water shortens the time before it starts boiling and producing condensed water. This water is heated with natural gas in the water heater, more cheaply than heating it with electricity in the distiller. Leaving some (hot) water in the bottom at the end of each use wastes the electricity used to heat it up. We are talking a few cents here, either way. At our electrical billing, I recall calculating the cost of distilled water at about 30 cents per gallon. (Forgive me if the power usage and cost data are a bit off, I am going from memory.)We are quite happy with this ROVSUN 6L distiller, and can recommend it. Our usage method was inspired both by our own ideas and the reports of other reviewers (thanks to all for reporting your experiences). Operated with a little care, it works fine, does not leak, and is easy to clean.I needed to be able to have distilled water for my A-Pap machine. Having so much difficulty buying gallons of distilled water right now was making me anxious.I use almost a gallon per week, so decided to get this on a trusted friend's advice.He has one, and offered to make me distilled water when I needed it, but I decided to go ahead and purchase it for my own use.It takes a while to process the water, but if you start with hot water, it does help to decrease the time needed.When in use, I put it in the laundry room and shut the door to help cut down the loud sound the machine makes.I would never suggest you walk away from it all together for safety's sake.I have processed several gallons now, and find it does a great job.To clean it, I just pour a small amount of white vinegar in the main chamber as soon as I remove the lid and then use a wet paper towel to wipe it down, as well as the inside of the lid.Once you've cleaned off the scale, use a clean, wet paper towel to rinse it.I then put it away in separate pieces so they all dry completely between uses.This is the 2nd distiller I've purchased. Seems to work just like the last one. Just under 4 hours to make a gallon.My other one was also an inexpensive off brand and this looks nearly identical. That one lasted 2.5 years of daily use. The heating element on the old one failed and it was blowing the circuit breaker in my house. Also the reset switch had quit working after only 6 months but that led me to getting a plug in wall timer so I could set how long the distiller runs. I definitely recommend a wall timer where you can set the run time. Then you don't need to rely on the reset switch as your on/off switch and you can set the time so there is a little water left in the bottom of the pot. Then you can just rinse it out instead of letting the residue get baked on. You still have to use vinegar every once in a while. The reset button is really just overheat switch so using a timer should eliminate the stress on that switch which is failure prone.This one came with a plastic jug which I like over the glass jug my other one came with. It is lighter and easier to pour and you can see the water level better because the glass ones have a metal ring right around the top. It is supposed to be made of safe plastics and it doesn't smell funny so I will probably keep using it. I pour the water into others containers anyway after I distill it. I also got an all copper container for my drinking water that I refrigerate. The copper supposedly ionizes the water and when it's cold it really tastes awesome. I have been doing this since 2017 and I see no reason to stop. The crap that accumulates in the distiller is visual evidence of what you are drinking without one.Delivery was fast. The email said it would take a couple weeks for delivery but it showed up in 2-3 days with Prime. The quality of this unit seems fine. Getting one that doesn't have a problem right out of the box is a win I think. I've read a lot of reviews and they all seem to have some reliability issues. If I get a few years out of this I will be happy. Even the Magahome ones that cost $250 have failures and they sell spare parts for them that are more than a whole new off brand distiller. So that's why I got another off brand one and we'll see how it goes. I will update this review when/if this unit fails.
