You will spend hours figuring out how to set it up because the instructions available on the manufacturer's website are mainly installation instructions and only very very basic operating instructions. They also have several tutorial videos available, which seem like they would be very helpful, but they are in Chinese with CHINESE subtitles. The cherry on top is that the support contact link on their website is broken and reading a thread on Cloudy Nights about this eADC it seems like it has been broken for at least a couple years.
After I finally got the correction right by guessing when to use Compensation and Tilt how much of each and got the fringing down to zero the correction did not last long. Within 5 minutes the red/blue fringe was 3 pixels on each side, within 10 minutes it was 7 pixels, the eADC over corrects at an aggressive rate. My correction would have lasted much longer if I'd just unplugged it and plugged it back in every 30-40 minutes and used it like a regular ADC. Both nights that I tried to use this thing I ended up taking it off and putting my 'dumb' ADC back on after wasting several hours of not-imaging time fiddling with it.
Don't waste your time and money on this, for this price range get yourself a very nice Pierro Astro ADC or similar instead.
