Function and operation were okay, but the unit stinks strongly of rubber and if it works the whole room smells like it. I just hope that this is harmless and eventually subsides. Therefore only 3 star for an otherwise in line with expectations device.
Want now after a few months added that the smell has subsided after a while and now is completely gone. Thus, the problem has done. Even otherwise I am satisfied with the device, up to my expectations. Thus, now the 4th star from me.
