Great mouse, but more cheaply made than previousSeptember 2, 2010 C. G. King(Horse Country, VA USA) After an intense gaming experience using a regular mouse, I was nearly crippled from the resulting pain and had to find an alternative. I'd had shoulder surgery and although I was recovering nicely, apparently still had weaker muscles than I realized because the next day I couldn't move my arm at all. Even though that cleared up with the help of PT, I decided I needed to try a trackball mouse for future computer activity and instantly fell in love with my new Logitech TrackMan Wheel mouse. I've never been interested in going back to a standard mouse even though my shoulder has long since healed.
After several years, though, that first Logitech trackball began having problems. It seemed I was perpetually having to remove the ball for cleaning. Although I never saw the 'crumbs' that must have become lodged, I sure felt them, as the ball movement would become jerky until I'd cleaned both the ball and the 'holder'. Even though the difference was slight, it felt like I was driving over a boulder and was very annoying.
Finally, I decided to spring for a new mouse of the same type and am very pleased with a couple of things. First, the ball movement is so smooth and quick I'm very glad I decided to start anew. The old ball had grown a bit sluggish even after cleaning, so I suppose the contact points were worn (and for good reason :). I didn't realize that the movement felt a bit heavy until I had installed this new mouse, which is much quicker, lighter feeling and more responsive. Secondly, since my desktop PC is several years old I have old connection ports. The PC works fine and doesn't need to be replaced, but doesn't have any more USB ports available and almost all accessories now attach via USB port. I am delighted that this mouse still provides the ability to install in PS2 mode via a supplied adapter. Hurray. That saves me having to buy a powered hub to add more USB ports.
On the downside, the construction on this mouse is not as good as the previous model. Although it looks identical but for being a slightly darker color, the wheel action on the new mouse is raspy rather than completely smooth as it was on the old model. I can actually hear the wheel move and can feel resistance. Although the ball is fine (even better than my old mouse) the wheel isn't as good. I can only hope it will deliver smoother action with use.
Still, I love this mouse. It causes no fatigue in either my hand or arm even after hours of use whether gaming or doing extensive photo editing where I have more precise control than with a regular mouse. I have arthritis in my thumbs, but have no pain whatsoever from using the ball and greatly appreciate that. All in all, I find this the best ergonomic mouse and very reliable. I highly recommend it even though the construction quality is not quite as high as my previous model.
It works very well and relieves stress on my wrist.September 1, 2010 Jeanette A. Partington(Houston,TX) This is my second Logitech track ball mouse. I got my first one quite a few years ago. I truly appreciate ergonomically designed keyboards and mice. My first track ball mouse finally died, after many good years of service. I just purchased a new Lenovo desk top computer and their standard corded mouse came with it. It was horrible to use. My best friend, Mary, heard about the situation and gifted me with the TrackMan Wheel for my birthday on 08/30. She could not have gotten me anything that I would have appreciated more. I loved my old mouse. This TrackMan Wheel is sleek and feels wonderful for my hand and wrist. I type a lot. Since I will only use ergonomic keyboards and mice, I have never had carpal tunnel problems.
If you have never experienced using a mouse like the TrackMan Wheel, please consider giving it a try. It may feel odd at first, but in an hour or less, you will more than likely be very comfortable using it. The price is very affordable and the mouse is very well constructed and will last for a long time.
