When my device was delivered, I was very excited about function and operation. The packaging was accordingly done the installation with very little effort. After the first few minutes of work, I've found, you need not regret the purchase. It runs really quietly, in stage 3 course loud but kept within limits. The Function `` drehbar``, very good. Only the arrangement of the switching function not gefäält. From 1 - 3 rotatable equal to static test. Otherwise top for my needs.
