Smooth ordering and prompt delivery. I could be able the track the order in each stage and be assured it was coming near. The distiller is simple to use. Just add water, plug in and press the green button to start. It cuts off automatically when finish, no over heating or burning. There is still a bit water around the bottom after it stops. First 2 or 3 cycles were used for cleaning the system. After that, the water tastes really sweet. We now use it every day, for teas, coffees and cooking, or just drink the pure water. I also use it for soap making, saving money to buy expensive distilled water as I did before. After one week, there are a lot of gunk and crystallised hard lime scales as expected of water in London area. I pour in hot water, add white vinegar and leave over night as I normally do when cleaning my kettle. Next morning, the stainless steel is sparkling clean. I will never go back to bottled water again. The quality seems good. We hope it will last.
