For months, I had my eye on the Logitech M570 Wireless Trackball. After all, it has more than 6,000 reviews on Amazon singing its praise, so it has to be great, right? Well, it definitely has its share of ups and downs.
On the positive side the wireless feature does not cause any lag time. It is very quick to respond. Now, I like the trackball to an extent, but I hate it because it feels so slow. If you are unfamiliar with a trackball it basically eliminates the need to move your hand to move the mouse. Your thumb controls the movement. Sadly, I found it to be quite slow.
If you were just surfing the web or doing light work, it's okay. However, if you work online like me where time is money, you do not want to be slowed down by your mouse. You want your mouse to be responsive to make you money.
I also hate the two navigation buttons. They are positioned where my forefinger constantly hits them. Lastly, I like that this came with a battery though. Unfortunately, the battery can't be changed. When the battery dies, you need a new mouse.
