I think in snow/ice each system can have errors. That is what i want to transport to my customers.
I think the GK QR is so good as otherones but who will believe an distributor in this case??
So i do the best thing i can do and let my customers the choice to change the system.
I inform everyone by phone, mail and internet.
With the result that all of them love the GK08 QR so much that they dont want to change up to this moment!
