Apart from that, seems nice and NC is working perfectly and design also looks good and comfortable. I think because of the material used and the holes in it, it kind of has the spring of well-made basketball shoes (weird I know). It doesnt pinch or pluck and i have sensitive skin! It has magnets so basically self held on roof then I routed the wires alongside cab and into cigarette lighter. So I went into the store and saw the "same " pair of Nike Tanjun sneakers. It fits him true to size and looks great. Jeremy Clarkson, Richard Hammond & James May are hilarious. It kind of defeats the purpose of going wireless if the phone has to be on you all the time to do a basic function like that. My foot is a 8 1/2 and the large fits perfect. That said, look for something else, and a different brand that actually follows through with their warranty.
