Review on 🖱️ Perixx PERIPAD-704 Wireless Touchpad - Large Portable Track Pad for Desktop and Laptop Users, 4.72x3.54x0.74 inches (Wireless), Black by Matthew Allen

This has to be the worst touchpad I've tried in a long time. It's possible the poor performance was caused by interference in the 2.4GHz band or by the distance of the receiver (2 feet away but no line of sight), but save your money. I'm still looking for a touchpad that could sit between a split keyboard that works on Windows and Linux with multiple gesture support.
