logitech MX ERGO Advanced Wireless Trackball for Windows PC and Mac (Renewed)Carbon Neutral Certified by SCS Global Services

My trackball journey began with the trusty M570, but the MX Ergo took things to the next level. Setup was effortless, Bluetooth was a welcome change (goodbye dongle!), and the build quality is top-notch—with a rubberized grip, metal accents, and a magnetic base that lets you adjust the angle to your liking. It feels sturdy, stays in place, and the battery seems to last forever. The programmable buttons are a game-changer for workflow, and I loved it enough to buy one for both work and home. If you’re a longtime trackball user or just trackball-curious, this is a serious step up.

I used to have the M570 trackball. Loved it. I had several, actually. But I felt it was time to get something new. Something possibly better? I didn't even know they made the MX Ergo. I did a little research and thought, "Yeah, I think I will get that one." So I did. When I got it, everything was smooth. No problems setting up or charging it, Solid buy.But then it was the clicking. The clicking that I could not get over how loud it was. Left click and it is all you hear after a while. I kept thinking, "I will get used to it, it'll go away, it's not that bad, oh well just deal with it, etc." But the clicking was distracting.It wasn't loud in the traditional sense, it is just... noticeable. When I buy a premium mouse, I don't want to have the clicking sound be super noticeable. It can absolutely be present, but not distracting. I watched a view videos on YouTube on how to quiet the clicker. I was like, "Naw, no way. Not for me. I just got this mouse and I am not taking it apart and messing around with those pieces inside. No way." Then last Saturday night, I said, "I am taking this thing apart and I messing with those pieces inside." Something had to be done.Now, I am an electronics person, so taking it apart and figuring out how to undo the ribbon cables and such was not so difficult. But, for some, I imagine it could be very difficult. Anyway, it was either that or soldering new silent switches on it. Which I was prepared to do and still might do. Anyway, I get inside the little clicker switch box, tinker around with the top metal piece that you need to lower and.... it worked. Put it back together and now I can focus on more important things. Like how silent the clicking is.... that's my life though. That's how it works. One constant revolving door.Anyway, still gave it five stars. Love the programmable buttons. Saves ample time and it truly feels better in your hand. Plus, unlike the M570 it has this rubbery coating that isn't just straight plastic. So that helps with the comfort. Feels solid too. The thing stays put and it's solid. Should have given it 4.5 stars cause of the clicking, but I know it won't bother everyone and it is a great mouse so 5 stars.

As a refurbished item, it's is very hard to tell it was ever used. The packaging was complete with manuals, parts, cables and of course the mouse. No scuffs, no gunk in the ball area scroll wheel, and everything works. It was a simple plug and play into my windows 10 laptop.The added Plus wedge made the Ergo a perfect match for my hand position. I drafted for 3 straight hours this morning and didn't need to stretch once. The ball seems to be identical to the last version in tracking and gunk collection. The only downside is the inability for me to push the ball out with just my pinky finger like I used to. Now I need to find myself a Bic pen to pop it out from underneath.Buttons are properly tacktile and clicky. Scroll wheel is much improved with less clack when zipping through a document, though the indents are more subtle and less annoying.Switching from Bluetooth to the mini receiver is seamless. Great for the docking station when I want to combine mouse and keyboard, and then grab the mouse and laptop to go to a meeting without worrying about anything sticking out of my laptop. The only downside is no place to store the receiver on the mouse itself. Luckily with the Bluetooth feature, I don't see myself taking the receiver out of the dock anyways.The texture on the mouse offers a solid grip, which I didn't realize I would need. Now that the mouse is at an angle, without the grip, my hand would probably constantly slide off.I'll update if the battery is less than stellar. If it hits anywhere close to 3 months of use, I'd be quite happy with it.Go ahead and give this a try, though I'd suggest getting it for under $70 as it's nowhere near a $99 mouse.
