No offense man but this product is NOT known by any of us. Maybe you should have a few members try the brakes before putting them out there. There's a lot of garbage out there and WE don't know the quality of your product, no offense. Notice that since you placed the add not a single member made a comment about them.
Nothing personal against you
I have been able to have a go in a car or two with the brakes fitted and they feel and perform solidly and smoothly. Maybe check some UK sites for reviews etc if you are looking for some experience before trying them out on your own?
