I agree: "OK", is about all one can say. It follows the manual pretty closely, and where the manual goes into detail, he does too. And where it doesn't...

The guy doing the presentation seems to be speaking extemporeanously, stumbles over his words too often [don't know why he didn't take the time to edit those out] and, in general, the discs seem to be cobbled together by someone in his living room, on a weekend.

I bought the discs hoping to get a good grounding on bones. Which was not forthcoming. Still, if you've really got your training wheels on with Carrara, it will do you no harm, and the price, as I recall, was moderate.
