Logitech - M570 Wireless Trackball Mouse - Gray/Blue

It's surprisingly hard to find thumb trackball mice, so there aren't a lot of competitors for this design - but this is an excellent mouse. In my opinion, the best. I use the computer daily, and often for long periods of time. This mouse design keeps my wrist from becoming fatigued or sore, or developing carpal tunnel. Its design is fully ergonomic. The fact it remains stationary also makes it extremely convenient for using with a laptop anywhere you like. The trackball ball is very easy to pop out (there's a small hole at the bottom of the mouse through which to do so) and clean with a microfiber cloth, along with the sensors in its bed which can easily become gunked up (no matter how clean your hands seem). A few months ago my cat knocked the mouse off the desk and one of the buttons popped out of alignment and wasn't clicking right. I dismantled the mouse's casing using a single small screwdriver and popped the plastic bits back into place and put the mouse back together without any issue. It's worked flawlessly again since. I just changed the battery for only the second time ever in Aug 2020, when I've owned the mouse since about Dec 2018. This is an unpopular opinion I guess, but I can't imagine gaming with any other mouse. No wrist fatigue, finite movement, and wireless to boot. Never had issue with lag or anything. The wireless USB dongle supports other Logitech wireless devices, so you only need the one dongle if you use a Logitech wireless keyboard or other peripheral. Super convenient. There is also a spot inside the battery compartment to store the USB dongle for convenient storage or for transit. The dongle is so small, however, I'm always able to get my laptop's case on with the dongle still plugged in. (How many times can I say "dongle"?) The Logitech software allows you to customize its sensitivity and button functions along with a ton of other settings. Super handy. If and when this one stops working, I will be buying another one.

The golf-ball sized trackball is on the side, and the other large finger switches are where you’d expect them to be. A scroll wheel sits between the pointer and middle finger, Two smaller buttons permit forward and backward navigation. Every action is modifiable using the downloadable app for either platform. Odd that the packaging doesn’t tell you to get the download. Arthritic fingers in this 70+ user likes this device which replaces a trackman center-ball corded Logitech of many years.

Love these trackballs -- what I don't get though is how Logitech hasn't updated it this item in over a decade (I've bought quite a few of them and have used probably 15 years). I recently switched to a different trackball (first new trackball (the MX Ergo) in almost 2 decades), but its still a Logitech. To be honest, I still prefer the "feel" of this model-- but, I also enjoy the features of the MX product line just enough more to switch. Great product and one of the best HID-type pointing devices ever made for any screen-based device! NOTE: This purchase was made to replace a left-behind trackball after relocating for a new contract (as have several of my purchases over the years). I've been using this model (M570) since the early- to mid-2000's.

I teach, and have a lot of papers to grade, all of which is done on the computer. When I developed a very painful bout of carpal tunnel syndrome, I analyzed the situation and decided that the problem was the angle of my wrist when I was moving the mouse. I had used a trackball in the past, so I researched and bought this one. It allows my hand to have an upward angle with respect to my wrist and within days I had significant improvement in the carpal tunnel issues, which are now, completely gone. I did take a bit of time to get used to moving the trackball with my thumb, but now that's fine. The device is wireless, with a small dongle that plugs into a USB port on my computer, and it works flawlessly. Because it is stationary, I can put it and my tablet on the same surface (see photo). I also have the option of removing the dongle and using the trackball with my laptop when I travel. Good Product!

Great starter point for the trackball transition. All feels solid construction seems good, I have not taken it apart but I'm sure there will be a need for cleaning at some point. It seems to come apart with basic tools, online reviews of other trackballs a test to a need for cleaning, so this may help in the future. I have not utilized all the functions of the device, but it has a few options for assigning some buttons for the thumb or something. Set up went easily enough, though I feel like I'm missing something when it comes to button assignments etc. The thing isn't really large, so folks with bigger hands might have less ease with positioning. It has a natural ergonomic position, and I find I put my hand right where it goes even if I feel like I'm off..

Takes almost no effort to use, ball is very smooth, comes with software that makes it easy to customize. I am still using my original Logitech trackball mice (one is more than 20 years old) so I suspect this one should last a while as well. The old ones don't have a scroll function, so this new one really helps with browsing and CAD. Would buy again.

I am extremely happy with this product. I do not like to keep moving mouse all over so I prefer this track ball, which can sit stationary at one place and I can surf all over any document or web page. What a relief!

Logitech Trackball is THE way to go! Don’t need a lot of real estate to operate, like a mouse. Waaay better than any mouse! We are using this on a HP Windows 10 pc. It comes with a little dongle to stick in a USB port & every works. Great price. More accurate than a mouse to operate. the dongle can be stored IN the battery compartment. Battery life is UNBELIEVABLY long! Has a scroll wheel and forward and back buttons.
