Since I always had misted windows in winter in the bedroom and wanted to dehumidify what handsome I ordered my 3 of these eggs. 2 for the bedroom about 18m² and one for the bathroom about 4m². In the bathroom you can clearly see, but that the air is quickly dry again in actually for the eggs to the master bedroom, they help. The windows fogged up considerably less. Nevertheless, you should probably listen to the room size recommendation on product and then rather take a big bag and lie down somewhere where you can not see it. I think then the effect is slightly better.
The indicator works, drying in the microwave also. Although I previously always the plug rausnehme down and place the egg with the opening facing upwards in a cup.
