Great update to the Trackman, keep old trackball.

Just purchased this to replace my aging Trackman Wheel that was having issues staying connected.
Overall, this is a great update to the cordless Trackman Wheel design with the addition of the on/off switch and the two additional buttons. The new wireless usb adapter is similar to the now standard mini wireless dongles, not the very large unit included with the previous model with it's 3ft usb cable.
With the mouse powered on and the usb wireless adapter plugged in, pairing was instantaneous.
My only nitpick about this new version is the new blue trackball. It doesn't feel nearly as smooth as the previous models' red trackball. It was very stiff feeling. So as a test, I swapped it with the red one from the old and not only did it fit flawlessly, it also both feels and tracks much better than the newer blue one.
Pros: same overall design two additional buttons on/off switch much improved and now smaller and truly wireless adapter
Cons: new blue trackball isn't nearly as smooth
If you're upgrading, or replacing an older Logitech Trackman(corded or cordless, shouldn't matter), hang on to the previous model's trackball to use with this and you'll be much happier!
What's great about it: Ease of setup and use.
What's not so great: New blue trackball doesn't track as well.
