Very good space manipulator. Very accurate, nice and heavy base. Sits perfectly even ot glass.
I use the wireless version at work for years and this one feels just the same. Very nice and heavy base with rubber at the bottom. Rubberised texture on the buttons and joystick, not slippery at all. I've used it in SolidWorks an SiemensNx for a long time and it makes drawing and manufacturing more comfortable and faster.
