Most of it is already said above. Very attractive design, the device is quiet, and it has a good suction power, about 15 minutes, if you treat them well with its 3.6 V batteries. The built-in battery (NiMh) are so-called "memory effect batteries," who constantly invites, so do not wait until the batteries are completely empty, loses much of suction, are minutes from the 15 times then fast only 2 min. The charging station has the distinct disadvantage that plugs and cables are "sealed" with the actual charging station, ie, these 2 parts a defect, then kan no longer load, so the instrument must be disposed of, unfortunately. In this day and age it is no longer appropriate.
