Well, I haven't had a chance to use it yet but our customer is happy as a pig in slop with it. He's had it installed on a Numerex 4040-24 dcc machine with a ph9 and a tool changer. For more information try: http://www.starrett.com/news_releaseApogee.htm and while you're there you can request more info.
He spent about 6 months looking over numerous software packages including PC-Dmis and Virtual Dmis before deciding on Apogee. It was competitively priced and had features he needed that were extra cost on the others.
I'll let you know more once we've had a chance to use it at the next calibration.
