Summary: Very Very nice
Review: the Logitech Cordless Trackman is easy to set up under OSX 10.2.6 the only thing you have to add the driver from the Apple site. But once dome it is a dream to use and I would not do with out it. I have for a momth om my G4 1 gig Power Mac and I totaly love it. I would tell all Mac users to go for it you will not be sorry.

Summary: Trackballs are no good
Review: The Logitech Cordless Trackman Wheel has the following drawbacks, some of them endemic to all trackballs, some of them unique to this product:1. For _precision_ mouse movements (such as using AutoCad), using the trackman ball with your thumb is like balancing a plate on a pin--I would rather use a touchpad. 2. At least in my office, the RF signal is "line of sight", so your receiver has to be within 2-3 feet of the device. 3. Get an optical mouse instead; more accuracy. 4. When the batteries run out, be prepared to navigate using your keyboard until you reinstall new batteries. 5. Only advantage I can see is if you have very limited desktop space.

Summary: Love the feel
Review: This cordless mouse simply feels great in my hand. I've owned about 10 different mouses and this one pleases me because it feels like part of my hand rather than part of the PC. I find that my thumb moves the trackball effortlessly while my index finger shifts almost without thought between the wheel and buttons. I seem to get consistent communication between the mouse and the receiver as I've not noticed any performance problems. Batteries last about a year and the mouse tells you when they are getting low by posting an alert. Also, I share this mouse with my two children. It's been dropped on a hardwood floor more than I probably know about. And it still works. Excellent design and reliable service. I hope this review helps.

Summary: Trackball and Wireless-------Unbeatable
Review: This is my first use of a trackball and I far prefer it to moving the whole mouse around. Very smooth action and precise. The wireless feature is perfect. Line of sight is not needed. Totally frees up the mouse with no cord. Just makes it a clearner operation. I got use to the trackball with my thumb in a day or two of use. Now I wouldn't trade for anything.

Summary: The best cordless mouse I've seen
Review: This is one of those surprisingly exciting purchases... I loved my old track-ball mouse until I upgraded from a PC to a laptop. The corded mouse just seemed impractical, but the only cordless track-balls I could find were the middle-finger ones. I finally found this thumb-ball one and I LOVE IT. One of the best parts is that you simply have to plug in the base, pop a battery in the mouse, and you're ready to roll (no pun intended.) There's nothing to download, nothing to install... no hassles whatsoever. I'm thrilled with my purchase.

Summary: The Mouse to end all Mice
Review: This is the greatest mouse ever to grace my palm. Many people have trouble using the mouse when they first sit down to try it. But now both my wife and I use one these wonders. There is no shuffling around the mouse to get to new screen real estate, there is no cord to get in the way, and you can comfortably lean back, rest it on your leg, and mouse away. It is too bad more companies don't follow suit, this is the best design I have ever used, and tryst me, I spend a lot of time mousing.

Summary: Best trackball ive ever used!!
Review: This is the greatest trackball ive ever used, motion is smooth and never jumps or skips across the screen. The included Mouseware software made it easy to install, and also included a nifty dinosaur cursor theme:) The built in scroll wheel works great and the fact this trackball is cordless made my desk alot neater. Logitech is GREAT:)

Summary: overall a great gadget
Review: This leftie with "piano fingers" is very satisfied with the Logitech Cordless Trackman Wheel. I use it right-handed (and think of it as left-brain crosstraining). Ergonomically I find it very comfortable - my hand rests easily over the unit with the forefinger on the left button, middle finger on the wheel, and ring finger on the right button. The cordless connection works flawlessly in both the PS/2 and USB ports. I've noticed no degradation in response at four feet of separation even when I rest the Trackman on my knee and the signal has to pass through an oak desk to get to the receiver. In terms of comfort, the lack of wrist and finger movement required by the design itself is greatly enhanced by the ability to place the Trackman at any angle, level, or orientation. My favorite is on my thigh beneath the desk. There is a bit of a learning curve if you've never used a Trackball device before. It's not unlike being used to driving a stick shift and then finding yourself in an automatic groping around for a non-existent clutch. For a while I caught myself instinctively sliding the Trackman in certain circumstances. But when you get it down, it is easier, more comfortable, and more efficient than mousework. In terms of accuracy, I would say that with the proper configuration, it is just as accurate as a mouse. It takes some time to get used to the trackball and you may need to tweak the acceleration and speed settings until you find the right balance that works for you. A couple things I'm not so crazy about: The scroll wheel doubles as a programmable third button. It is so close in height to the left and right buttons and sandwiched so tightly between them that I find it difficult to use it as a button without inadvertently hitting the left or right click button (and I have long, skinny fingers). And finally, if you're using this on a laptop with a built-in pointing device, you may not be able to fully tweak the Trackman settings if you run it through the PS/2 port. I got that warning when I set it up on my Thinkpad (with an integrated touchpad and trackpoint). Fortunately I had a free USB port I could dedicate to the remote receiver (the adapters you need for either the USB or PS/2 connection are included). So laptop users who don't have a free USB port may find that they are unable to fully configure the Trackman. This could be a problem because it's something you'll really want to get just right. And skip the CD-ROM installation and just go to their website to register and download the latest version of the drivers and software
