Ive had mine 4 years now and its saved me a fortune; in fact its earned me money 
Back to around 2001 for me, when it was a serial lead with a single licence for the laptop

I've used it constantly since, had great support (especially from Uwe and Sebastian) and got a great deal when upgrading from the old serial lead to the latest CAN+ cable.
They deserve success in my view...the product is superb.
If everyone buys cheap rip-off cables then they wil stop developing VCDS and we all lose out.
