Writing a review on the Logitech Wireless Trackball M570 has turned out to be one of the most enjoyable writing experiences I have had in a long time. A friend of mine suggested that I try using a trackball mouse to help relieve the beginning symptoms of carpal tunnel syndrome (he'd seen me rubbing my wrists a lot). I had been using a computer quite heavily for about a year before I began to experience that familiar burning sensation and numbness in my wrist that others often spoke about.
After doing a little research, I knew that if something wasn't done to solve the problem it was only going to get worse and may eventually lead to surgery. I had never used a wireless trackball mouse, and to be frank, had never even considered such a device, but the pain was getting worse and I was getting desperate. Despite the high price, I chose Logitech to run my little experiment and I've got to say, I’m glad I did. The information that follows will review both the good points and the bad that I considered important when using this product. I hope they will help you make an informed decision.
• Carpal Tunnel: I began to experience immediate relief of my wrist pain and although they don’t advertise this benefit, I believe they should. This is the main reason I bought this device and so far it seems to be helping me tremendously.
• Ball Location: The trackball itself is located to the side and is controlled by the thumb. There were choices of finger controlled balls, but I felt the thumb control would be better for my wrist pain (Logitech seems to be one of the few companies that do this).
• Ergonomics: I have fairly large hands and was surprised that they fit quite comfortably around the device. The ball itself moves quite easily and the click buttons are located in the same area as a regular mouse so I don’t really have to adjust my hand at all. There is also a scroll wheel, of which I am very glad of. After working at a computer for a while I do believe that choosing the proper ergonomic chairs, keyboards and other accessories make all the difference in the world in relation to comfort and injury prevention.
• Customizable Buttons: You can go to the Logitech website and download software that allows you to adjust ball speed and assign features to the buttons. I was able to download it very fast and very easy. It works like a charm.
• Battery: One AA battery (included) is required to operate the device and Logitech says the trackball mouse can go for up to 18 months without a battery change. The battery was dated several years ahead of the date that I received the product on, which I found very reassuring. There is even an on/off switch on the bottom to help conserve the battery life.
• Wireless Capability: I was pleasantly surprised of how much I liked the fact that I wasn’t tethered to my desktop computer by a cord. The device came with a small receiver that can be plugged into any USB port. Logitech also says that you can use up to five more devices (wireless keyboard, etc.) from this one receiver. So far I have had no problems whatsoever with delays or being out of range even though I have used it from all around my room. The specs actually say the device can work on any computer from up to 30 ft. away!
• Work From Anywhere: I’ve used the Logitech Wireless Trackball M570 from my sofa, from chairs and while lying on my bed. It seems to work well from anywhere, and still no wrist pain.
• Works For Mac and PC: I own a PC, but am considering buying a Mac. It’s good to know that I won't have to worry about this not working with it. It is compatible with Windows XP, 7 and Vista on a PC and the Mac OS on a Mac.
• Learning Curve: It did take me a little while to get used to operating a trackball mouse. I found myself trying to move it around like a regular mouse, but this habit went away after a few days.
• Scrolling: The scroll wheel seems a little stiff and squeaky (if those are the right words) but seems to work just fine.
• Price: I bought it for right at $50 on Amazon. I thought this was kind of steep at first, but if it would help my wrist pain the cost would be worth it.
Although there are a couple of pet peeves with this product it has helped relieve the pain in my wrists a great deal, which is the reason I bought it for in the first place. This is my first experience with such a device and with Logitech itself and it has been a pleasant one so far. The good points heavily outweigh the bad on this particular wireless trackball mouse and I would definitely recommend it to anyone wanting to alleviate wrist pain.
Logitech Trackball - Update #1 (1-24-2011)
I first published this review on December 19, 2010 and have been using the trackball mouse ever sense. It's only been a little over a month, but I feel that I must re-emphasize how a device like this can help anyone that has carpal tunnel syndrome or similar wrist pain; the burning and numbness is virtually gone and I couldn't be happier. I also anticipated the battery would be giving me trouble by this point, but I was wrong. The M570 from Logitech is still a must in any computer user's arsenal.
