Con:
We bought 2 of these pads in two different sizes and not only were the thicknesses very different, but the measurements were not correct. The 5x7 was thicker and actually needed a minor trim. The 4x6 was thin and smaller than the stated size. 
Pro:
The larger one that was thicker is perfect for our family room where people tend to sit on the floor.  The pad doesn’t slide around on our wood floors.
