Customer Ratings & Reviews

Got this mouse when I bought my MacBook. It's great because with Bootcamp and switching between Mac OS and Windows, after setting up the bluetooth connections within each all I have to do is press the connection button to switch between profiles to use the mouse on either platform easily without any dongles. Also the raised and angled magnetic platform makes it very comfortable to use.

I missed using a trackball, but I had tendonitis problems and switched to a DXT ergonomic mouse. I thought about building a tilting base for a trackball, but when I saw Logitech was offering a tilting trackball I was all in. Disappointment followed. All that was in the box was the trackball, a micro USB cable, and a couple of pieces of paper: battery disposal instructions, and safety instructions in 6 languages. They went in the trash. Contrary to what's in the documentation I was able to scrape up, there was no Unifying receiver. No clue that it would work with Blue Tooth (not that I can use it with my desktop PC). No clue how to use the "hinged" base, which is apparently just a magnetic base with two possible positions, one normal and one with a slight tilt. The "wedge" gives me more tilt, but not quite as much as I can use. No clue how to assign the buttons (which you can probably only do in Mac or Windows anyway). Logitech has always been the gold standard with me for ergonomics, but now they're batting three strikes: for summarily discontinuing the Squeezebox line, for summarily discontinuing the Harmony line, and now, for the worst product documentation I have ever received from a new purchased product. The trackball works OK, but rather than buy more I think I'll just build those tilting bases for my old trackballs

Excellent touch and feel. Very precise. Great control options.

Love it and very easy on my wrist. A little pricey but it is worth it.

One the best trackball mouse I bought easy setup too

it was a bit to pay for a mouse. still getting used to the feel. the contour may not work for all hand sizes.

This is a great mouse. It flows great. I like the fact that you can tilt it for better ergonomics.

Good enough for basic use only if all you do is surf the web and click on links. It's well built and the ball rolls smooth with no friction. Definitely not designed for office work, programming or any task that requires your hand to be on the mouse a lot and do a lot of highlight copy and paste. People use their dominant index finger as a precise tool. With this mouse, you are forced to roll with your thumb. The USB cable only charges the device, it does NOT also act as wired. This is an issue because if you lose the very tiny itty bitty usb receiver, then you are left with a well built $99 mouse you can't use until you get a replacement receiver because the cable does not act as wired, it just charges the device. Overall feel is just like having your hand on a half cut coconut. Too tall and too wide. Rolling with your thumb feels like a struggle. Also, I don't see the point of the tilt function if it only tilts to 20 degree. If it tilts, might as well go all the way to 90 degree with it.

Works great. I actually really the difference compared to the blue version without an angle.

nice mouse battery life is amazing. it feels different at first.

Good mouse alternative helping relieve carpel tunnel

I've been using Logitech trackballs for years now and this latest model is my favorite of them all.

The best purchase I ever made, I lov this mouse. It has lived up to all they said it would.

Overall I like it, but it is missing a few things to make it perfect. First, it charges via micro USB. Why would you make a device that doesn't use the standard USB-C? Second, the scroll wheel doesn't have the ability to free spin like the wheel on the Triathlon. This option makes it so much easier to scroll documents with multiple pages. Third, there is no place to store the dongle in the body of the Ergo, like you can on virtually every other Logitech device. Lastly, the base plate is magnetic and there are only 2 options to position this device. Why not have the base plate mounted permanently and able to be set at multiple angles? This way there is no chance of losing it and you have more options. Like I said, it's good but could be better.

This is the best Trackball mouse for Business and regular computing. I like them so much I bought another one for my laptop. They are awesome and worth the cost.

Great mouse, really like the ergonomics of the design.

The best mouse I’ve ever had. Able to tailor to me usage needs.

Easy connectivity , good quality, very nicely constructed and very user friendly. Love it

I bought these to replace my old Logitech trackball. The old one wasn't registering clicks as it should have been (that was the second one that had done that after some time). I like the feel, shape, and weight of this one. It allows me to sit on my couch with my laptop and do whatever I need. I hope that this one lasts longer than the last two I bought, especially for the price.

I DJ and use it for my computer it works pretty well
