In comparison to the old device, this is also significantly better, the optical detection is much faster and more reliable. In the Kobil device transmission was frequently interrupted and had to start over again.
Here me is that never happened. The TAN generator has hold on the back of two rubber nipples to him while in the detection position - very good!
I can not say anything because I do not use it more than the other functions. The font I can well recognize (a normal LCD display).
For the price you wanted a solid device and exactly what I expected.
