Logitech MX ERGO Wireless Laser Trackball - Black

I've been using trackballs for a long time now. This is the best one so far. Pros: Rechargeable Bluetooth AND usb dongle Can use with multiple computers at the same time, easy to switch between them new angel is great Cons: The base it sits on to be angled is a little interesting. It's just a magnetic plate and base that sets the angle. Something more fixed and solid might have been a better solution. However, after a few months of use, it hasn't been as big of an issue as I thought it would. Every once in a while the base pops off when traveling. If it was just stationary on a desk, I don't think it'd be an issue at all. Overall, Love it!

WOW, this is a great track ball. I still have my M570 and it still work just fine. I bought this one for the ERGO option and was not disappointed. The button option to slow the icon is a nice extra I do use to my surprise. Rubberized roller wheel I very much like. I use mine with the angle riser on most of the time, but not when I switch to my laptop. The ease of changing the angle is nice and the magnet is strong so not to slip off. USB charging is nice I haven't had to charge it yet. finally the Bluetooth option is great not having to pull the tiny receiver to use on my laptop is very nice. just a touch of the top button and its working.

Overall, it is a good trackball. I was looking for a blue tooth trackball that I liked which was not very easy. This trackball is a bit pricey but it is worth it. It can shift down or up depending on your preference. I got use to this very quickly. It doesn't use traditional batteries so you have to keep it charged via a USB cable. The ONLY thing I have found out I do not like about this trackball is the battery life. MUCH SHORTER than using batteries like the old wireless Logitech Trackballs. It dies on me because I don't think to plug in a WIRELESS device every few days. But it works fine on a USB cable while it is charging so it isn't too bad.
