Here’s our ergonomic video review of the day. Check out “Best Ergonomic Mouse? Logitech M570 Review.” I bought this mouse last year and tried it for a month. I want to love trackballs but at least for me this is not the best mouse. However, if you are into trackballs, this mouse is an EXCELLENT value! You can often find it for less than $25 with shipping.
