Not bad but...,
This review is from: Logitech M570 Wireless Trackball - Graphite [UK Model] (Accessory)
This trackball was purchased to replace a Logitech Cordless Trackman Optical which has now been discontinued.
The trackball is controlled by thumb movement as opposed to the Cordless Trackman which was controlled by the index and middle fingers. I have found that controlling the trackball with the thumb sacrifices some accuracy in cursor movement and can become uncomfortable after prolonged use.
The wireless unifying receiver is small enough to be deposited within the trackball for convenience and portability. I have noticed that the performance of the trackball can be affected if there is close interference with the receiver, relocating the receiver to another USB port helped resolve this in my case.
The software from Logitech's website also enables the 4 buttons and wheel to be easily customised to your preferred functions. There is also a more detailed battery life indicator displaying days remaining, which I find useful. Only 1 AA battery is required to power the trackball and is said to last up to 18 months. There is also a power switch on the bottom of the trackball to save power when note in use.
This is not a bad trackball but I feel it is a step down from my previous device which had more functions and felt more comfortable to use.
