Very Accurate using 2 star alignment. I do alignment with 6 mm eyepiece (240x) when using my 280mm manual dob. I'll usually do a slight tweak by going to a known object below 60degree, scroll to realignment and hit enter. If you observe in weather below 50F, you will need a 12V powersonic battery and modified standard power jack to connect to the battery ( if observing away from an electrical outlet) or buy the adapter on the sky commander web site. Below 50F and with the 9V battery, the screen is blank because the internal heater won't function.
After two years, I still don't use 80% of the features ( I'm not hard core and my scope and skies limit what I can see. Currently Messier, ngc, hic, IC and doubles are all I really use). It's sort of like a new car infotainment system. When driving on the road I only need am/fm radio and cd, the rest is useless expensive crap. I'm not saying these astronomy computers and software are crap, but they contain way too many features which I'll probably never use. Maybe if I had a an 18 inch mirror and viewed from very dark skies, I would think differently.
The old crude sky commander works just fine for me. The only thing which would make it better ( other than being controlled telepathically) is if it had great big knobs and switches so I could operate controls while wearing heavy winter gloves. Fingers get a tad cold after 4 hours when temp is below 35F. I must be showing my age.
