I am very unhappy: 1. In the following description was to read: Flachschirmhaube, etc ........ continuously variable operation via slide switch. That was the first thing that is wrong. It's a simple step switch with 4 levels, on which you can switch the fan. 2. The assembly instructions has something in common with a guessing game. Only better hand sketches without even a note in writing what should mean something. It takes too long to understand what to do and there really can. As nothing with "self-explanatory instructions". 3. My old hood was much more stable with less cheap plastic. The AEG hood definitely makes a very unstable feeling and at the price of 700th I would no longer buy and therefore also make any recommendation to buy.
