Then I have the ROTEK Amazon purchases (best in price / performance) and I can only say, sensational. in the first 2 days I had to !! 4 !! Times the box empty (2.5 liters). Now I have a humidity of about 60% and it smells no longer damp in the basement. If increasing the humidity again, run the ROTEK easy overnight and already the container is refilled! The instruction manual is explained in German and very good !!
A strong buy recommendation, I do not see any defects
