The textures are nice and the pieces are exactly what would be expected. The default scale works perfectly for Hot Wheels cars and still looks good when used with 32mm models.
It is a bit disappointing that the barriers are rectangular prisms but their graphics have a definite top and bottom. It would have been nice to make a single large set of barriers with arrows on them and just place them as either right or left facing arrows as needed instead of needing to make a batch of left arrow barriers and right arrow barriers. I would have also appreciated a flat fold option for the barriers like what was done on the turrets in the Auto Combat Gun Turrets pack. Those things are what kept this from being a 5 star review.
