Logitech M570 Wireless Trackball Mouse Ergonomic Design with Sculpted Right-Hand Shape Compatible with Apple Mac Microsoft USB Unifying

I bought one of these back in 2007, and put in a AA. I had no idea at the time that I had just purchased something that would be with me for a LONG time. To be honest, I've got ADHD and ASD, and the shiny blue, perfectly round heavy ball looked amazing to play with, and super tempting. I told myself I would NOT play with this fancy toy until the mouse broke. This would be a very long exercise in keeping my word to myself and resisting temptation. This mouse was super easy to use, I just plugged in the little dongle, and it was ready to go. Loved how quick it was to plug and play, and while the tracker ball took a little getting used to, considering I had only used the movable kind of mouse before, I found it fairly intuitive and easily adapted to using it. This mouse has customizable buttons on it, that I was able to set things to for playing MMOs, It was quick and dependable for letting me get high scores on flash games. I am an artist, and one day my Wacom tablet broke, and I just.... used the mouse. Because of the smoothness of the tracker ball, I was able to draw with it and get the lines smooth and right where I wanted them. After a year or so, the mouse stopped working! I was confused at first, and then I remembered the battery! I pulled out the battery and swapped out for another AA, and it was right back to how it was before! Darn, no sparkly tempting blue orb for me. This mouse outlasted my computer, another computer, countless laptops, and is now on another desktop.... All easy swaps of the little dongle, and no fuss. This mouse started out being plugged into a computer with XP, then was moved to one with Vista, then Windows 7, then landed on Windows 10. I've used it for art, for regular computer things, for gaming, all sorts of things... All waiting to play with the blue orb of temptation. Every year or so I would need to replace the battery, and each time I was hopeful that the thing had FINALLY worn out... I would pull it apart, use a screwdriver to clear out pet hair, whatever fluff had gotten in the sensors, put it back together, add a fresh battery, and it was always as good as new. I can't tell you how many times it's been dropped, flat out thrown (I have three kids, who are super destructive) I've moved a couple of times, got married, had kids my life is COMPLETELY DIFFERENT than when I bought this thing. At one point a hot glue gun had been set on it before it was cool, and it had MELTED a hole through the plastic... but everything still worked 100% fine. I've pretty much given up on this thing EVER giving out on me. I figure it will outlive me at this point. Aliens in 10,000 years will excavate the earth, find this stupid mouse, with its a shiny blue orb of temptation, plug in the dongle (that magically will fit their systems), and start using the mouse to navigate their space ship. So this fall, when the mouse stops working, I'm like "When was the last time I changed the battery? I don't remember. Guess it's time to do that again (I've said a year, but in truth it depends, and I've gotten anywhere from 10 months to 18 months on a battery). I pull it apart, unscrew the case, clean all the components and sensors, put it back together, put a fresh battery in, and... IT DOESN'T WORK. I'm shocked at first. I assume there's something wrong with the battery. I try a new fresh battery, and it STILL doesn't work. At this point, I check to make sure I didn't mess something up putting it back together because I don't believe it's given out. It's been THIRTEEN YEARS with this thing not having issues... THIRTEEN YEARS!!! Literally teared up and felt bad throwing this away (minus the shiny orb of temptation of course). I pop on Amazon and order a new one, the exact same thing. So far this one is exactly as good and easy to use as the old one, and I figure in 13 years or so I'll probably order a third. Read more

I've been using the predecessor to this trackball. It had a red ball & a tethered USB unit so the trackball itself could be wireless. It started eating up AA batteries faster & faster. When I was replacing them every couple weeks & having to create a new "handshake" between the trackball & the tethtered unit (almost daily), I decided to replace it. These units last a long time, but eventually they'll die (by "long time," I mean about 8-10 years). I read the reviews of this unit before buying to be sure their quality hadn't slipped, and I was momentarily hesitant when I read a review that said the ball didn't move as smoothly in this one as it did with prior models. I opted to take a chance anyway, and I'm glad I did. First off, the unit is identical in size to my previous model, so the comfort level was there. The ball was, indeed, stiff when I first got it out of the box. However, after about 5 mins. of use, it glided smoothly and effortlessly -- just like the one I'd been using for so many years. I'm a writer, but I also work in Photoshop and alter photos...sometimes, working on some very fine details. I've had no issues using the new trackball for those jobs. The biggest change between this trackball and my previous model is that this does not have a tethtered USB unit. It has a tiny little USB plug that slips into my laptop and that's all. Logitech has made it easier for me to move from my desk to the sofa to just about any other place by not having that tethered wireless unit hanging from a USB port. One of the best parts of using Logitech is my experience with their customer service. About 15 years ago, I had a different Logitech trackball (the ball was on top & moved by multiple fingers instead of a thumb ball), and it was not performing reliably (it was not wireless). I called their customer service department, and they shipped me a replacement trackball based solely on the serial number of the trackball that was defective. I didn't have to show them a receipt or jump through a bunch of hoops. The person on the phone was quite honest. He said that their units were now being made in China, and the quality control may have slipped when building the unit I had. It was refreshing to hear some genunine honesty from a company that had shipped their production overseas. Anyway, I'm a loyal Logitech user because they support their products, they perform as advertised and they're very easy to set up. The previous wireless trackball I owned came with a CD to upload the software. This did not. I had to go to the Logitech site to download the software. That's not a problem, but I thought I would mention it to cover all bases. I don't know how this works on a Windows computer. I use a MacBook Pro (latest model), and my previous Logitech trackball had been hooked up to an older wedge-shaped iMac, a new flat-screen iMac and now my laptop. The trackball worked flawlessly with all of them. When the time comes to replace this computer in a few years, I fully expect that this trackball will still be functioning properly and will easily transfer to the new computer. Read more
