If you own the original tabmate controller the first thing you'll notice about the new tabmate is the missing joystick. I love the joystick and it's been replaced with a shortcut button for the Hand tool (temporary switch) which is easy enough to get used to. There's a wheel on the new tabmate assigned to zoom but I am accustomed to having zoom in/out on the forward buttons of the older tabmate. It's easy to customize the new tabmate to operate more along the lines of the older tabmate though so I've assigned zoom to the front buttons and brush size to the wheel. All the extra buttons are nice on this new tabmate and the bluetooth connectivity seems to work well enough.
Both Tabmates (original and bluetooth) work at the same time and have their own menus under the preferences tab in Clip Studio Paint.
I placed my order from Canada and received the package from Amazon Japan three days later, so shipping is pretty fast. Import duties are included in the cost and came to about $5 Canadian.
