Logitech Wireless Trackball M570

Most people don’t spend a lot of time pondering their computer mouse. This is evident as the “cheapness” of the standard mice that come with new PCs seems to be reaching ever-greater heights. I suppose that as long as the mouse works, that is enough for most users. I admit, however, that I am not a typical PC user (AAII’s IT department can attest to that). Furthermore, I am part of the minority of people who prefer a trackball to a traditional mouse. This has been the case since I got my first laptop 17 years ago when I was a sophomore in college. Over these last 17 years, all but one of the trackballs I have used have been from Logitech. For the last several months I have been using Logitech’s latest trackball offering, the Wireless Trackball M570. While it is difficult to improve on such a mature design, I have been pleased with what I have seen.

Installation & Setup

Setting up the M570 was about as easy as could be. The trackball uses one AA battery, which was included in the packaging. The M570 is wireless, which means you are not tethered to your PC by a cord. The mouse comes with a USB wireless receiver that you plug into your computer. Depending on the number of USB slots you have, this could be an issue, since you effectively lose one. Once the receiver was plugged in, I was up and running. While there is no software you are required to install to use the M570, you can download Logitech’s free SetPoint (Windows) or Control Center (Mac) software to program the trackball buttons and adjust settings.


If you have never used a trackball before, the M570 will take some getting used to. It is somewhat amusing to see the looks on the faces of people who try to use my PC. They recoil from the trackball almost as one would from a snake. However, for someone familiar with Logitech trackball devices, you will find it very similar in shape. It is designed with the trackball, buttons and scroll wheel positioned to fit your right hand (sorry, lefties).

To navigate the pointer you use your thumb to roll the trackball. If you find yourself outshooting your mark with the pointer, you can adjust the sensitivity of the trackball with the optional free Logitech software. The trackball itself glides effortlessly, and I feel that a trackball is much more precise than a traditional mouse, a plus for gamers and graphic designers. If the trackball begins to stick, you simply flip the M570 over, pop out the trackball with a pen or pencil, wipe it off, clean the contacts inside the case, and pop the ball back in.

Another reason why I prefer a trackball is that you don’t need as much desktop space to move around as you do with a mouse. The location of a trackball is fixed, which makes it preferable for those with space limits or keyboard trays. Furthermore, you don’t even need a flat, solid surface to use a trackball, meaning you can use them virtually anywhere.

From an ergonomic standpoint, I think that trackballs are more comfortable to use than a traditional mouse. While it may be that I have just become accustomed to using a trackball, I find that my wrist starts to hurt after using a mouse for just a short period of time. With a trackball, however, I never experience any discomfort.


The M570 is a five-button mouse. Like many mice these days, there is a scroll wheel for quicker up and down navigation of documents and Web pages. I found the scroll wheel to be a little stiff, but I think the M570 is designed that way, since the scroll wheel is also a middle-click button and the stiffness prevents accidental scrolling while middle-clicking. Flanking the scroll wheel are the typical right- and left-click buttons. Logitech has also added “back” and “forward” buttons to the M570, which are invaluable if you do a lot of Web browsing.

Using Logitech’s setup software, you can program the buttons to fit your needs and adjust the sensitivity of the cursor.

Unifying Receiver

The USB Unifying wireless receiver you plug in to operate the M570 also allows you to add a compatible keyboard, number pad or even another mouse to the same receiver without having to take up additional USB ports.

Battery Life

One of my biggest complaints with other wireless Logitech trackballs I have used has been the battery life. Since wireless trackballs are not plugged into the PC, they require a separate power source, usually two AA or AAA batteries. Past experience had me replacing the batteries seemingly every few months. After several months of use, I have not yet had to replace the battery in the M570 and, according to Logitech, I shouldn’t have to for 18 months of “typical” use. If this is truly the case, it would be a significant improvement over previous models.

Final Verdict

As I said from the onset, trackballs cater to a niche group of users. Personally, I think they are more comfortable than traditional mice, an important consideration for someone with carpal tunnel issues. My only complaint with the M570 is the stiffness of the scroll wheel, which is only a slight annoyance. The ability to connect additional wireless devices with the Unifying receiver, as well as the vastly improved battery life, makes the Logitech Wireless Trackball M570 the best trackball I have ever used.

I have been using trackballs (mostly Logitech) for 20 years, first on PC's, then on my iMac which I've had for four years.

When I bought the Mac, it came with the Apple mouse, which I immediately replaced with a wired trackball. After about 20 months of use it failed and Logitech replaced it with the wireless model. My only complaint is with the battery life, as it seems to need replacing on a monthly basis ( it uses 1 AA battery). My only other beef is with the size of the unit. Once when it failed, I was out of fresh batteries, so after talking to Logitech tech support, I plugged in my old PC trackball. My hand is not oversize but it seems to fit the old PC trackball better.

Kudos to Logitech support!

I recently bought the 570 and I like it better than the older wired version, which I have used for a couple years now -- better ergo and it has buttons for page up and down, which make browsing easier. I used to have wrist pain (with a typical mouse) and it disappeared with this trackball mouse. You can spend a lot for an ergo mouse, but this one is very reasonable and worked very well for me.
