Agree with above. Most light aircraft autopilots I prefer to leave alone especially for the approach. I really don't like the idea of the AP managing the roll and the pitch being manual for an approach. I have not come across this before but in my head I can see someone death gripping the controls and the autopilot not being able to control, and when it disconnects (or doesn't from my experience) the person is in such tunnel vision they don't notice things going wrong.
2 axis (roll + pitch) autopilots aren't going to coordinate turns for you, with the exception maybe being in aircraft that have the ailerons and rudder linked where you can get away without using rudder anyway.
