Fantastic precision!!! The only trackball I would use.

Purchased the MX ERGO to address the wrist pain I had while using traditional mice. I was skeptical at first, but the combination of the angle adjustment and ball navigation are quite good. I originally thought my productivity would be drastically lowered due to the lack of extra buttons, but the logitech software allows for the buttons to have up to 5 additional functions tied to them via gestures. There are also no issues with tracking I have experienced in the month I have used the mouse. I cannot speak of its gaming capability (as I haven't had the opportunity to play games with it), but it's quite the boon in office. The build of the product is great with a matte feel and decent heft. Again, the angle adjustment of the MX ergo makes it really comfy. The only issue is a bit warmth that develops at the palm over extended use. I am not sure what causes this. Highly recommended.

Wow, this mouse is so amazing! It absolutely makes using the computer, in my case primarily laptops, more enjoyable and efficient. The hand position is extremely comfortable. Overall, this is a fantastic product, it's a little expensive at Best Buy, but it's a premium product that serves an important function as we are on our computers all the time.

The mouse is great for those with larger hands and the ability to change it's grip. I like the fact that it does not use a battery. I had to buy another one because I dropped it and broke spin wheel.

This is my third one of these. Helped resolved rsi in my wrists, the ball works smoothly and the sizing of the mouse is perfect if you have larger hands. I have one for both of my laptops and when my first one broke I replaced it with the same mouse! Really can’t complain, maybe wish you could connect with just Bluetooth

I got this on a whim after a few online reviews saying that it was a good trackball and I was interested in trying something new; I usually haven't given trackballs a shot because they seem so in the way and are often imprecise in my experience. Also I was bound out for a 15 hour train ride, and the last time I used a mouse in my seat, it didn't go well (I stubbornly refuse to use the trackpad on my laptop). It definitely is a learning process to get used to this, I would say about a week before I felt like it was second nature. But it eventually became comfortable to me, even more than the trusty mouse I usually use. The precision mode is perfect to click in stubborn text boxes and where I need a pixel-by-pixel click. The scroll wheel works perfectly, and it has all the buttons I'm used to with a Logitech mouse. The only hassle so far is the occasional cleaning of the ball, but not too bad. The one-star knockoff is pretty much still my getting used to the form factor of this trackball.

Great wireless mouse. The angle adjustment works great to fit your hand and it responds fast with no lag. The entire reason why I want the track ball. Charge lasts a long time. Definitely worth the money.

This is the best mouse ever invented. The whole world should use these. No arm fatigue from the friction of moving the mouse across surfaces, so its easier to work in smaller spaces (think: airline seats). Battery life is great. Charges quickly. And connects to multiple devices at once. Simply the best!

This has an added benefit that made this a very worthwhile purchase. It can connect to two devices that can switch by the press of a button. And there is also a function that allows you to switch monitors between two computers like an extended monitor. When you move the mouse to the edge of the screen, it will automatically connect to the other PC. I never thought I was going to get comfortable with a trackball mouse. But it came pretty naturally. I mainly got it for my 2nd PC where I have a stacking monitor between the two, but didn’t want another standard mouse to need space for. And this worked even better with its features, to use it for both computers.

Honestly the best mouse i’ve used so far, not needing a mouse pad or a ton of room to move around is perfect for my editing workflow when on location.

I cannot use a regular mouse anymore without them bothering my wrist. This mouse has been a blessing, since it not only helped the angle of my wrist, it also reduces my movement thanks to the trackball. The only downside is that, as with trackball mouses, you need to remove the ball from time to time to manually clean the movement sensors (whenever you start getting erratic behaviour). This is charged thru USB cable, so all good on that end.

It works well for me, not a lot of movement compared to a regular mouse. It also helps with mobility issues in my hand.

I had other Logitech trackballs but this one is the BEST EVER. Super ergonomic and adjustable. Precision feeling. Well, it has exactly what you are looking in an ergonomic device.

Pros: Most comfortable trackball I've owned, and Logitech's new Options setup software (on the Mac at least) is really the pinnacle of cursor control software that I've ever experienced. The feature where you can control the tilt of the entire unit with the magnetic add-on angle footer and leaning of the hand position is just flat ingenious. Cons: I went to the web site to download the user manual, and there isn't one. Honestly, I'm not sure what I think I would find in the manual if it existed though because the darn thing really doesn't need a manual (can't say the same for the Craft keyboard I bought at the same time though, and it didn't have a manual either)

I loved the roller ball mouse. Logitech is a top of the line mouse but I wanted a Bluetooth mouse and this roller ball mouse wasn't so that is why we returned it.

this ergonomic mouse is perfect for my needs. easy to use and very comfortable on the hand and wrist

I am just now discovering this trackball mouse. Thus far, it has exceeded my expectations. It works with both my devices without inserting the receiver with the associated device.

Even though I returned the one that I bought and it was replaced due to not accepting the new driver for it and continually saying no driver found by windows the one that replaced it works fine and drivers loaded perfectly and were also found by windows. Thank you to the guys at the Store I shop at in Yakima WA.

Logitech cost a bit but relieved so much pain in my wrist and elbow! Love the rolling ball! I really like wireless and battery less capabilities!

Take a little bit of getting used to. This is my first ball-mouse. But holy crap...This might just do the trick. I don't think it will entirely replace my traditional mouse, for work stuff, but I think for my regular day-to-day, this is the way to go. I am a retoucher by trade, and find myself going back to my Microsoft Precision Mouse for actual work...But, normal browsing and usage (outside of Photoshop) I think this is a winner. I strongly recommend using the included dongle for connection, as the bluetooth connection seems to have a little tiny bit of jitters. Anyway, a day of usage and my wrists already feel better. It feels a little light and the included stand to add height slips a little...not perfect...but pretty close.
