I just tested programming with my Brios P-Up, with mini Pro and Target fitting software. When I used "Connect" button, it immediately recognized HAs, although they weren't shown in the list of available devices. It is an interesting experience. So far, the biggest benefits are fine tuning the curves to recommended values using smaller frequency steps (I guess my audi used just 10 steps, with finer tuning you can get closer to recommended curves), and also adjusting few options (reducing wind-block, adding more gain for phone calls etc.). I have to admit there are a lot of features I am not familiar with, so I stayed away from them for now.
