Ok, so go start to brush and already have to say as that this bar is completely unstable. With a slight pressure is after this (flexes) and therefore does not give a good feeling.
Then, I had to push a little harder, because a job was a bit dirty and stubborn, the top rod pushed further into the lower, the metal splintered and was razor-sharp way.
Impossible! Have the part again packed into the box and bring it to the post office tomorrow! Return it!
The cleaning power and spin are very good works. Only with such a shaky bar is all not really to use.
