Logitech Wireless Trackball M570

I am selling this trackball professionally. And the customers who trust me always have the same reaction: "expensive for "a mouse"". And for the first three days, they curse me for always trying to slide the M570 across the desk surface. But afterwards they wish tar and feathers to the inventor of the classic computer mouse...and they don't want anything else. This trackball is the alternative to a mouse for EVERYONE who A) sometimes use the laptop in the sofa or bed B) has little space on his desk C) want absolute precision from a mouse (in eg games) D) configurable keys on his trackball. A plus is the Unifying receiver so that multiple Logitech input devices can be connected Only downside I think is that wireless is not always a must. I would like to see this product again with wire, so I have 7 of these at home on my devices, but they are no longer for sale.

Once you get used to it, this trackball is very easy to use. No more mouse for me. Shame about the quality of the buttons. This is for both the wired and wireless version. After a while these work poorly. You notice this especially when you want to select something. Hopefully they do something about this because this isn't just with me.

The perfect combination of mouse and trackball, very ergonomic design, no more painful wrist/arm. You can work with it very precisely, both on the Internet and in other programs, even graphics programs. Tested for several hours daily and encountered no problems. In the beginning it takes some getting used to to operate the trackball and scroller in combination, but once you get used to it, fantastic! the two back and forward buttons are also super handy when browsing the internet, making this just a little bit smoother. A purchase with not the slightest bit of regret! super!
