I got Intuos Pro PTH651 and my pen has starting to malfunction [It wouldn't register the button press as well anymore.]
I want to buy Wacom Pro Pen 3D but I noticed there's no compatibility with PTH651 but it supports Wacom Intuos Pro (PTH460, PTH660, PTH660P, PTH860, PTH860P).So I don't know if I should take the risk or not. There's Airbrush Pen that supports PTH651 but it's out of stock.
