Outwardly looks the part of a very high quality. But the on / off buttons are deficient. In my geliefertem device no electrical function was possible. Also, do not even contain a replacement blades. And all this for just 50 euros. Probably you pay 30 euros just for the name Eheim. The rest is worth just 15 euro. Well, that's it I have noticed during the returns procedure. The blade change goes smoothly and easily. I bought a normal glass scraper made of plastic for 2,95 Euro inclusive 10 spare blades. A vibration and lighting on the doctor I do not need.
