A scope company manufactures a product. A moving company sells a service. In business school, if you were to use a service company model to analyze a manufacturing company you would fail the exercise.
I've learned the hard way to never argue with Graham. Whats up dude, you know I love you man.......but. It could be said the the scope provides in some sense of the word a "service" to it's customer. And, again, it's the customer that decides what products and services are of good quality, and like this thread proves beyond any shadow of any doubt, customers opinions vary.
