I have been using this product for a few months. It does the job well and seems sturdy. I let it run at night, it stops automatically once all water is evaporated (3 to 4 hours). Then in the morning I put the pure water in glass bottles. The water tastes much better than from the tap! I would recommend to buy some spare filters and to change them very 2 months.To clean it, I use a tissue to remove the dirt. Once every two weeks I let boil water with a bit of white vinegar, it removes all the limescale and it looks brand new again!
