Summary: Only down side is goes through batteries slightly faster than other similar models of this mouse. But to save a few dollars in batteries I bought a set of rechargeable batteries and a charger for said batteries.
It's the Trackman Wheel you love, but the range is really short
6 February 2014
Summary: This is the wireless version of the legendary Logitech Track Wheel we love, but I should have paid more attention to the comments in the reviews about the limited range. If I have the receiver even 3 feet away the response suffers. I have placed the receiver right under my monitor about a foot away.
Summary: I just ordered the wired version for my netbook. Much smaller package over all. Wish they would update the wireless version, it certainly needs better battery life and smaller receiver. No other decent choices out there...
Pros: Accurate, comfortable, easy to use. Greatly reduces stress on my hand/wrist/arm.
Cons: Receiver is HUGE, with a long cord, almost as big as the mouse. Would be excellent for netbook or laptop if it had a tiny microreceiver like the newer Logitech mice.
Summary: Only other quality trackball was the Microsoft one, which is no longer made. I can't use mice for very long without my wrist and arm hurting, so I hope Logitech continues this one. Own several wired and wireless versions of this trackball.
Pros: Ergonomic, comfortable to use. Wireless. Very accurate.
Cons: Needs to be relatively close without obstruction to the transmitter. two - four feet. Batteries need replacing every 4-6 weeks of heavy use --recommend high quality lithium rechargeable batteries. There is no off button.
Summary: My family drops this mouse and the wired version a lot (Couch + Coffee table set up). Both versions have taken more than 20 drops and still work well. The wireless versions ball even though clunkier stays in when dropped approximately 3.5 feet.
Pros: Wireless, no fatigue from dragging your wrist across a surface. Can take a beating and multiple drops on the floor.
Cons: This mouse is not designed as tightly fit as the wired version of the same type. The ball wobbles a little bit in it's slot than the wired version.
