This product does everything as advertised. I especially like the fact that it turns itself off once it runs out of water. I only use this to distill water, so I only run it at the top temperature of 108 degrees.A few things I have found that may be helpful:After each use, pour a 1/4 cup of vinegar into pot and leave for a half hour, this will eliminate any large de scaling operations.Start by using hot water from your tap, this will save about an hour of processing time for each 4 litre batch.Never pull the top off without waiting for the unit to cool down, the residual steam is dangerous.Try to use this when electricity rates are at their lowest, usually 7 PM to 7 AM, at 750 watts this unit uses a fair amount of electricity.
