The Quality of the Mats are great no issues there. The width of the Tarmac Highway is to small for 28mm [1/43. 1/46. 1/53] scale vehicles. Hotwheels [1/64] just fits on to the roads not much of a gap either side of the road. In my honest opinion this would suit 10mm or 6mm scale vehicles. Which thankfully I will be using with this. Also you really do need two sets of these mats to get any decent type of race track set up.
