Ok here are some pics of the pads for comparision purposes. Hope these help and you decide for yourself !!!!
The Azzpadz have a built in curve. They are hard to get a pic of the thickness of the pad, its just a bit smaller than a nickel
This is the Azzpadz thickness best I could do as it is a curved pad
Here is the Skeletools pad
I bought an extra set of pads so I sometimes double them up as I said before.
Hope this helps some of you
