Review on Perixx PERIPRO-706 Wireless Trackball Mouse With 0.98 Inch Built-In Trackball And Detachable Gel Palm Rest by Matt Dyen

I specifically asked Perixx support what the sensor resolution of this trackball would be. I was informed it was 400/1000 (DPI), which would be nice for both fast and fine movement speeds, I thought. After waiting a couple of months for this trackball to release, I ordered it and was immediately disappointed - no sensor resolution toggle. The movement is far too slow for modern use (1920 x 1080 pixel displays are at the least commonplace nowadays; that's about 4"+ to go across the display with a roughly 1" ball diameter). The buttons seems nice and crisp to click. The addition of a scroll wheel that clicks as a third button is definitely an improvement over other competitor trackballs.
