We use this machine now for a few weeks, it is the whole day in operation. With 25-30 coffee drinkers in the department you have to fill the machine 2 times per day to satisfy the thirst of coffee. The coffee always tastes fresh from the first to the last cup and in a few seconds in the cup. If you want to switch off at night and warm up the coffee again in the morning you should check that discs and the riser pipe was removed, otherwise the coffee flows again through the old coffee grounds :-) It is better if you remove the discs and the riser pipe immediately after the passage, which increases the service life of the silicone gasket under the riser is. Good is also the automatic shutdown (thermal fuse at the bottom of the base plate), if the machine is empty and you forget off. The cleaning of the machine is a bit more complicated than that of a small filter machine, but every time you have to do 5-10 minutes until everything is cleaned and filled. Then you have to wait 20-25 minutes until the machine has finished. But when you consider that we have previously filled the small machine 4-5 times per day, the total cost is much lower. What is missing? A thermostat, where you can adjust the temperature. The level indicator is also somewhat difficult to read. The last 2-3 cups can only be drained when you tip the machine slightly.
