I have to think the dash pads are all made in the same place... China.
The differences are found in the sellers, customer satisfaction, retail price, and shipping charges.
There's some rubber molded ones and Ultimate Rides ones and maybe another. The rubber molded ones are heavy and you can see some air bubbles on the surface if you look close. And they just look different. The UR ones are not as good quality.
The Just Dashes ones are very nice. But the cost is higher since they are hand made individually by Americans so the labor cost is higher.
