I had fun playing around with the endless customizable features of the Logitech Cordless Mouseman. It felt comfortable in my hand and performed just as well as it looked and felt. The scroll wheel also very much came in handy when browsing the web and viewing long documents. I loved the Mousemans Back and Forward browser buttons. This had me hooked on using the Back and Forward buttons convient located on the side of the Mouseman instead of moving all the way up to the top-right corner of my browser to press Back. Button.
Now, I just use my thumb and press a button to navigate thru webpages. I also found that this mouse is built like a rock. It survived an accidental fall from my desk onto the floor. Usually, I never drop things, but, this was a surprise to see that an optical product didnt break as easily as another optical mice and trackballs. The only problem I had with the Mouseman Cordless was that I couldnt use my existing Logitech receiver. I had to use the included receiver for the Trackman Cordless since the MX Duos receiver didnt accept the signal from the Cordless Trackman.
This was an excellent trackball and caused me but one issue and that was that I couldnt use my existing MX Duos receiver with the Cordless Trackman.
