As part of today’s Prime Day Deals, Amazon has the Logitech M570 Wireless Trackball for only $20 for Prime members. That’s about $7.50 off the regular price and the lowest we’ve seen for it.
The unique shape supports your hand and it stays in one place so you can move the cursor without moving your arm. “Just roll the ball with your thumb and click. Precision never felt so comfortable.” Also, if you find that you have old arcade style games on your computer, this bad boy is really the only way you can play them (like Centipede). Rated 4.5/5 stars by over 8,000 Amazon shoppers.
