Have used one for years Bob. They work as advertised, but the problem is that, if a planet is so low down that an ADC can help, it will also be so low down that the turbulence will generally give you crap results. An ADC can only help on those very rare excellent nights - and then it is really worthwhile if you take luminance images as well as RGB, or use an OSC.
