The very large deficit of this device lies in its volume. The wolf makes noise like a flex - really - he is at the top of the noisiest craft equipment in our house - with Flex and E chainsaw.
I bought an adapter weihnachliches sprits to which is also super works only with earplugs for children handlebar (ie appliance is not suitable in society)
Unfortunately, the volume of this unit destroys everything. Used in the basement, it makes a very good wolf service, but only to use there.
I take the wolf for the great and rapid size reduction of my Hack portions with closed doors in the basement
