Customer Ratings & Reviews

The pad included in the Plus version really does make a difference, so I'm glad I got it. I had used the G900 Chaos Spectrum mice for a couple years for office and schoolwork. I prefer this mouse at the moment. Also, I have large hands, which this mouse fits very well. The buttons are placed intuitively and are easy to click. The scroll wheel is clearly premium and well-balanced between noise, ease of use, and just enough grip to support horizontal scrolling and middle-button scrolling. The Logitech Options software seems to be put together well, but it'll be used minimally for me. I can't install it on the work computer, and my home PC doesn't use most of the applicable software. Innovative, nonetheless. At least for large hands, the ergonomics are great. I don't necessarily have pain, but my right forearm felt immediate relief from using this mouse. There's a ton of value in this mouse and it's worth the price, but the trackball could use some improvement. It's fairly light and stops a little too easily and somewhat unpredictably. To that end, I might buy a second one to try to mod it with a different ball and bearings to see if I can improve it.

Great feel and speed with ease of use. I would recommend to anyone looking for an ergonomic mouse.

For most days, I'm working on a PC at my desk. This trackball reduces stress on my arm and hand. The angle of the trackball can be flat or angled - like you're shaking someone's hand. To me, it feels quite natural and reduces any stress on my arm. If you're looking for a new "mouse", this may be the one to get. You will need to get used to using a trackball though, but that learning curve is short.

I have had one of these years ago and had forgotten how much I liked it. Uses only the space of the footprint without needing to push a mouse around. Paired seamlessly with my system via bluetooth, easy to change settings, autobackup from manufacturer, can have two custom settings for different uses, has gross versus precision mode accessed by thumb button for ease and quickness. Is adjustable for different hand/wrist preferences. I can't find anything to complain about at all.

Super good mouse! Easy on the hand as well. A biy weird to get used to since its mostly thumb action unlike a regular mouse but after a while its amazing! I got it to try something different out and dont regret it!

This mouse has been the answer I required. My wrist was constanlty in pain from using the regular mouse. I never really liked how the old style roller ball mouses functioned. This one they have everything right and its design allows my hand to comfortably rest thus removing the strain and stress. This is a great mouse especially as Ive experienced as my wrist no longer throbs after 10 hours behind the keyboard.

Love it easy to connect Feels solid not like I can break it (most people call me a bull in a china shop) Nice ergonomics. I had the cheaper trackball with the blue ball and this one beats that one hands down my wrists dont hurt after using it for hrs. The ball feels smoother and more precise and I love the quick change of going between my pc and cell phone. With the quick click of the top number button. I will be buying one for my desk at the office.

You all already know the good stuff about it so I’ll be the one on here to be negative nancy. I only took 1 star off for all of the stuff below because I think it still deserves about 3.5, so I rounded up to 4. Here’s my list of qualms with the thing. A lot of it’s preference but a lot of it is also what I consider is universally disappointing: - the magnetic tilt function is useless and a danger to other electronics. I’d prefer a fixed position and a variety pack of angled wedges instead. (Though I like how heavy the thing is and it never tilts on accident). Also, nowhere to store the unifying receiver, probably because the magnet would kill it. Just too many parts to keep track of and it would suck to travel with this, so it will stay at home. - the power switch on the bottom is extremely flimsy and therefore I will need to limit the amount of times I switch it on/off. The battery life is so good it doesn’t even make sense to turn it off though, so... crisis averted? - the precision button is a cool feature that I use a ton, but the button itself sucks and you really gotta mash it to actuate it. - the clicky buttons and scroll wheel are really loud. But I think here I’m just being picky... - I’m going to replace the included trackball with one from perixx. This one just doesn’t do it for me. Feels like it’s made out of friction. Also, when you attempt to spin the ball fast to flick the cursor across 3 monitors, you’ll only make it halfway through 1. I find that I have to spin it a lot for it to move very far. It is unable to pick up really fast movements. Hopefully a new ball will solve this, but unfortunately I think it’s the sensors themselves that can’t keep up.. - the rubber material on the grippy part is nice but I think time will tell that this was a bad design decision. It will erode it away and it will get sticky. - you have to create a Logitech account just to download the software. But, to my surprise, the software doesn’t suck. This was something I was very worried about, knowing my history of frustration with other products like the G600 and how crap the software for it was. Overall, not worth the $100 price tag. I’d call it fair at about $50. But, what other options for us trackball users are there? If you want a thumb trackball mouse, there is only Logitech, unless you want a garbage Chinese knockoff brand. It’s a great mouse though, don’t get me wrong. I’d recommend it.

very nice mouse. for the money, it has the number of features I'd expect. Two devices simultaneous, ergo adjustments, performance mode (which is cool), & a few buttons which makes navigating a bit easier. Some features I don't use, but when & if I do need them, they're great, especially for creative applications I use at work. My only tik would be you must charge this device. It has good battery, but I don't feel like it's a device with recharging to be a must, one day, this will just be a wired mouse.

This was for my wife. She loves these. Bought this one to replace one just like it that she accidentally dropped in a container of liquid. To replace it, she wanted another one just like it. Not only are we a purchaser of this item, but we are a repeat customer. It is not just one of those things that seems good at first, but she likes this product after extended use of one just like it!

This is an excellent trackball. It’s built like a tank and is very configurable from an ergonomic standpoint. The software allows you to program various keys - a very handy feature whose value is not evident until you set the device up the way you like it. Admittedly, it’s a bit pricey but, IMO, this trackball will be worth the difference in cost over its M570 sibling if it lasts as long as I expect it to.

Got a surface tablet and needed a blue tooth mouse due to limited USB ports. This mouse connects via the laptop Bluetooth without using a USB port. Love the trackball. It requires a zero footprint. You never have to move it around. Which makes it perfect for laptops while setting in a comfy chair or couch while surfing or working. It has 2 channels for two different laptops. The price is a little high but I got mine on sale for $20 off.

This trackball is my go to for my laptop computer. The scroll wheel can be pushed side to side for side scrolling. It also includes two extra buttons and a sensitivity button. It works quit a while between charges. The trackball comes with an ergonomic, magnetic base that when attached, tilts the entire thing to one side for comfort of the wrist. Love it

The Logitech MX ERGO mouse is awesome. I got hooked on trackballs when I was in their Air Force, working in Cheyenne Mountain's Command Center in the 80's. This device makes input both extremely easy and precise as well as offering superior ergonomics that reduce wrist strain.

I am finally satisfied with a mouse! It has all the features I need, a rollerball for my thumb that lets me move ACROSS the page without needing to move my arm, a top scroller so I can move DOWN the page as well as back and forward buttons. I really like that it has spacers that can be placed under the mouse to raise it up at an angle so it is more ergonomic. There are even a few buttons I don't use that other users might find handy. Overall, it's the best mouse I've had in over 30+ years!

My husband swears by this mouse. He wont use anything else. He left the last one on a trip and came home with a brand new one. He wont leave this mouse for ANYTHING.

Wow. This thing is great. Never thought I’d be this excited about a mouse, but while working from home every little bit helps. Being able to switch between 2 computers is a big plus. You get used to the trackball in about a half hour. Extremely customizable. Just a really great product. If you use Mac i would also get their Mac keyboard. The two work together well.

If you have experience using a trackball you will love this. If you have not used one I would recommend this for your initiation. Easy to configure and use the wireless connection was seamless as it was recognized and ready to use shortly after installed. What I appreciate even more is it is rechargeable. The charge seems to last forever which adds to it's beauty.

If you ever use the trackball version of a mouse you will never go back. This one is VERY smooth, has multiple formats accessible by a single button push, is wireless (I sit with it in my lap across the room and surf in more comfort. No carpal tunnel with this mouse! If you throw the screen to your smart TV you can sit across the room and REALLY enjoy "big screen" computing!

I was looking for a mouse a while and eventually came down to this one. It is easy to and connec to any computer. Charging doesnt take long and the battery a good while.
