Menzer ETS 150, a cheap alternative to Mirka Deros and Festool ETS

After having problems with my brand new Festool ETS, it has broken twice in 6 months, I decided to buy this cheap alternative, to have it as a spare when my Festool ETS is in service.
    I am very impressed with this sander, it is very powerful and has almoust no vibration. I give it a hard test: I sanded an alder cookie cut with the chainsaw. It took me around 8 minute to smooth it with 80 grit sandpaper. I push it down very hard and it did not stop, it doesn't have so sensible sensors like Festool.
