Customer Ratings & Reviews

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.

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

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.

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!

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.

I have used many trackball devices from Logitech over the years, and this is the best one yet. It is comfortable to the hand, especially with the part that renders it to be at an angle. I only wish Logitech could add three device support to this as they have to the MX Vertical and others.

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.

I work on the computer all day long and my wrist started hurting really bad with traditional mouse. I decided to buy this mx ergo plus mouse because i read that the angle of the wrist being more vertical and less wrist motion would help. It really does help! After the first few days my wrist immediately felt better, and now several months after my wrist continues to feel great. I love how its rechargeable and I dont have to buy batteries. Also, the track ball obly took 1 day to get use to using. I was afraid it was going to be difficult but its quite easy to adjust to.

I love this mouse. Going from a regular mouse to this trackball mouse has benefited me greatly for music production and the typical internet browsing. I’ve heard some complain about their thumb being uncomfortable or fatiguing but it must be after 2+ hours because I have yet to have my thumb strain so much that it interferes with my work. If you want to save space on your desk or want a more accurate cursor, this mouse is for you. After about a week you’ll be adjusted to this style of mouse.

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've been in IT for about 20 years now and have developed mild carpal tunnel syndrome from it and this mouse really helps not only relieve some of the symptoms but also helps me from re-injuring problematic parts of my wrist. It's not a cure all, and I still have some pain after working a few hours straight and I would recommend using a wrist brace when the pain starts up, but this mouse helps those episodes from happening as frequently as they used to. Lastly, this is the second one I've purchased since I was so impressed with how well the first one helped me out.

I've used a Logitech M570 trackball for years for everything but graphics (which requires dexterity my thumb doesn't have). When it came time to replace my third one I upgraded to this. I love the adjustable angle feature -- much more ergonomic. I haven't played with any of the programmable buttons or other special features yet, but the "precision tracking" button above the ball is an excellent solution for the dexterity issue. I wouldn't recommend this more expensive model to anyone who hasn't yet decided if a trackball is for them, but for those who have, it's worth the extra money to upgrade from the 570.

Got this to replace one that broke after less than a year. Was hesitant on the "ergonomic design" but after using it, I had to get the same as a replacement. I hope this one lasts longer than the first but the Best Buy Warranty should take care of that. Good value only if on sale.

I've been using track-ball mice since I was in highschool (2001). This is by far the best investment I have made in peripheral devices in ages. I only wish they had had something this ergonomic when I was playing Delta Force 2 and Delta Force LAN Warrior. The built in angling mechanisms make this perhaps THE most comfortable mouse experience I have had. More so than Disney, and everyone want to go to Disney. But this is significantly cheaper, plus no long lines. To add, you've never experienced the infinite mouse pad until you've used a track ball mouse.

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!

I love this mouse. So smooth, quick, ergonomic heaven, and can be mapped onto two computers. I toggle between two computers with great ease.

It took a while to get used to using the scroll ball but after about a week it was seamless. Only thing I wish this product had more shortcut keys.
