+ No bending
+ Wiping performance well (but it is also better!)
+ Contrary to other reviews I was sufficiently well with the true round wiper in the corners
But the all-important Contra:
+ The link between Mob (the "Frans thing") and the Mobhalterung is an absolute lack of structure and the small "noses" which will keep the mob in Mobkopf so microscopically small that you can watch it as they fail in service. The first connections still folded smoothly, then the connection was similar to a bent Tupperdose that you press all around and never approaching.
The Mobhalterung is not to get in the trade (only the mob itself), so that one would be forced to failure Mobkopfes to buy a whole new set. For me, after 3 months of the event. For me clear Keywords: Quality desert! Set throw away, buy new?!? No more sustainable philosophy.
This was not an option for me. I'd rather see around for tougher and better proven products!
