As a fan of white cats, I had to buy this product, of course. A good side effect it should also humidify the air. Prima. Since we have a very bad air in the office, so I chose this product. I must say, it was clear from the outset that it will show more of the room little effect in. Anyway, it is a beautiful decoration for my desk. The container should I fill every 2nd day at least.. This I do with Brita filtered water to avoid lime stains. After 2 days, the ear tips of Mietzi have turned yellow and once the Mietzi gets wet it is no longer so beautiful white, but rather beige. The whole is also quite unstable. Colleagues have already overturned several times :( Delivery (shipment) took over a week!
