Customer Ratings & Reviews

I love the accuracy and feel of this mouse! It has a lithium battery that lasts a long time. I love how i can connect it to 2 devices via bluetooth and just have to click a button to switch between the devices.

Easy to connect and use. The rechargeable battery is great so far.

This trackball is awesome and great improvement over previous models. I've been using the logitech Trackball predecessors for years. Oh the comfort! I gave it a 4 for value because this model is on the higher end. I gave it a 4 for ease of use, because you have to be a trackball user to understand and appreciate the usability of this product. I keep a regular shake and wiggle mouse on hand for times when I'm collaborating and need to let someone else "drive". I call it my "Guest Mouse". My point id people just can't figure out how to use this product in 5 minutes. As for me I'm thinking of buying another one for my home office during COVID, since I had to leave this one at work.

This product was my first trackball. Ergonomics were great; the additional 10-degree wedge was good to use at times, and at times good not to use. I enjoyed the toggle connecting between two devices (e.g., work computer; personal computer). Unfortunately, after about 1.75 years of daily use, I started experiencing the double-click issue where the device registers a multiple click while holding down the primary click button. It seems to be a common issue for the product as far as what I can gather from Internet forums. So that's the only downside -- quite annoying that it happens quite often, so I'm going to look for another mouse/trackball.

I had an m75 before this, but here's my review. The ergo plate and extra wedge are awesome, really helped with certain positions. The extra button on the side is mappable, which is amazing. Gives you one extra function. No DPI switch, unless you map it to the button. The ball does take a bit of force to start rolling, therefore its not the most accurate when moving slowly. Fixed easily using the "precision mode" for the extra button. The switches are not as tactile as the m75, which I was slightly disappointed in. They also are very flush, so its hard sometimes to know if your hand is correct. Forward/back buttons are small and off to the side, a little too far away in my opinion. All in all, it's a great product. I've been using this style of trackball for years and years, I only wish they make a "gaming" version someday. Or at least improve the rollers the ball rests on to be smoother.

I love the design and not having to move the mouse around

i love this mouse. if your a track ball type this is the way to go. i like the look and feel and it has some weight that doesn't slide around. This would be perfect if stationary but not as a traveling mouse. although you can disconnect the heavy pad it clicks too.

I sit in a recliner to game, and I have a bad shoulder that was just getting worn out by the way my arm was positioned. Anymore the 30 minutes, and arm was screaming. I had been using Logitechs older trackball on and off for years, except I found it a bit clunky for gaming, but I decided to give the new Logitech trackball a shot. I'm not exaggerating when I say this mouse changed my life. After a week of using this mouse, I barley noticed any discomfort. After a month, my arm feels like it's finally starting to heal. The flexibility of wrist position really makes a diffrence and, even with short fingers, I don't strain to have full control.

Love this style of mouse. Excellent features. I especially love the quick button for slowing the cursor down to do precision work. The 3 separate degrees of tilt function is great for when you feel stiff and relieves some of the pressure from the wrist. Logitech needs to better dongles for their Bluetooth though. It has to be in direct line of sight or it creates connection issues. If you can manage that setup, it’s an excellent mouse.

Very comfortable great battery life, a bit heavy but amazing mouse for long work hours on the computer

I'm very pleased with this trackball. I had one years ago and was hesitant to try one again, but with the Best Buy return policy I gave it a try. I love it. It is responsive. I have two screens and regularly have to pick up the mouse because I have to move it too far. This solves this problem. It is ergonomic so I don't get tired using it. I recommend this.

Tried this as I have limited room on desk for mouse movement. Now that I have used this mouse, I prefer it over a typical mouse like the one in my office. It can connect to two different computers and change between them with the click of a button which is great to go between my home computer and my work laptop

After doing research on a more ergonomic mouse solution, I ended up with this. They say these mice are better than the vertical options. In the past I could have never imagined myself using a trackball mouse, and probably even poked fun at those who did, but I was lost then. Now I am found. Build quality is excellent. I do wish the buttons were more plentiful though, and the ones that are there could be placed just a bit better, but overall I’d certainly recommend this to anyone looking for a more ergonomic option. Also nice that when you get it from Best Buy you get the additional wedge to tilt it up a bit higher if you’re into that kind of thing.

I was a little hesitant to spend this much on a mouse. After all, how much better could it be? As someone who has never used a trackball, this took a little bit of time for me to get used to it. But now I love this thing. I'm on the computer all day for work and I can't live without it. I like the ability to be able to use it on two different devices. Its pretty simple to switch from one to the other by clicking on the middle button below the wheel. My only gripe, I wish it came with a case. But then it would also probably cost more.

Great ergonomic mouse. Seamlessly switches between two computers on your desk making work flow easier. Works great on my Mac as well as on my Surface Studio.

This smells works great. The ergonomic style really lessens hand fatigue. I use this mouse every day and I don't think I've charged it in a month.

Sent from the heavens! Switched from MX Master 3 due to repetitive motion strain in my wrist which was limiting my function and capabilities of my dominant hand due to pain. No regrets! Over a month and a half and my writ is healing naturally and shoulders/neck are loosening up as well. Took about one working day to get the hang of the tracking ball. High hopes LogiTech will revise this model the the scrolling wheel of the MX Master 3 as this scroller is clunky.

Bought this as a replacement to my last ergonomic mouse. This one is comfortable and easy to use. I like the way it is adjustable to keep your positions of your hand in perfect alignment.

I love the ability to use this wirelessly with more than one device. Also, being able to adjust the angle is wonderful.

For many the first hurdle will be getting used to a mouse that doesn't move. This does take a little adjustment time. I have had two M570 models but the added ability to tilt up to 30-degress does take stress out of the wrist joint, thus decreasing potential carpel tunnel as the wrist and arm are in a more natural position. The ergonomic design fits well into the palm of the hand whether male or female. The scroll wheel on this model can now scroll left-right, a very nice feature. Also the ability to change the speed of the cursor at the touch of a button so as to move nearly pixel by pixel; a great idea for editing photos, graphic designs or doing art. A very good addition to the Logitech lineup.
