I wish I could, but I'm trying really hard to understand myself.
I think they released V 2.0 long time ago, maybe they should just come up with a new name for all this. Maybe that's what they're trying to do by calling all those products "INSPECT", in one package, which would be a great idea if true.
I could understand a car company has many products for all the markets, for example but even the Sigma dot connectors are starting to get confused here.
I like this really great approach can you explain?
