Fair enough, if your business relies on CS. Think the point is that he doesn't need to, hence hasn't bothered coming on here to be subjected to the likes of yourself and another select few. Wise move really, he'd only get baited into an argument
The thing is if you are confident in your products and your own knowledge then why bother that I or whoever popup and question a product or a service?
It should be water off a ducks back. So I say there a Leda copy, or question the pricing structure or how you can tell people they can be tuned for a specific tyre etc. etc.
If you can explain why they arent and tell me how much they cost and give a valid reason for any particular claim then I can except it.
My own personal opinion is that Andy feels out of his depth when answering technical questions.
