A good hairdryer, but with little quirks

The hairdryer does the job, and I would like to get rid of two criticisms.
1. The heat output is lower at other hairdryers with the same output of 1800 watts. Before we zulegten us this hairdryer, we had another, also from Bosch, which was hot.
2. To grasp the handle with the entire hand always leads to the fact that one or another of the three switch is actuated unintentionally when blow-drying. Here you have to develop its own tactics to exclude this.
Because both issues just mentioned 1 point deduction.
