Customer Ratings & Reviews

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'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.

Great for people dealing with carpal tunnel. Changing the angle helps with not overworking the same part of the wrist

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.

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

Can't believe I have been doing CAD/BIM for 30 years without one of this. They always look like too much stress on the thumb. I was so wrong! I decided to try it because I developed a bad shoulder pain. Pain is gone! Was a little weird at the beginning (and I even thought about returning it) but after a couple of weeks I can't even remember what I didn't like. My only complaint could be is that is not as sensible for super accurate selections (I think the way the ball sits on the socket has to do with this), but other than that I really recommend this mouse.

Makes navigating and scrolling so much easier. I barely have to move. Connected very easily via USB and Bluetooth.

Absolutely love this mouse. This is, bar none, the best mouse I have ever held. It is very ergonomic and super comfortable; I’m partial to trackball mice and some aren’t; if you are this is the best one I’ve used and if you’re not or are looking for a first trackball mouse this is the perfect balance of cost and function- you’ll never need another. The adjustable function makes it nice for using for a while since you can change the angle if your wrist ever did get tired (it probably won’t)

I normally use regular or steelseries mouse for playing video games but for general use I use this one. It has 2 modes regular and precision ( regular sensitivity and SUPER sensitive) which helps when your trying to click on specific things. It also has 2 connection memory so you can connect it to two different computers for settings 1 and 2. It is a great investment and really helps prevent things like carpal tunnel. It even comes with a magnetic adjuster to make it more comfortable based on your wrist placement... I dont use it but its helpful!

New base reminds me of old fashion shoes with lifts attached. The new base seems to make using the trackball more comfortable. The trackball has always been my go-to mouse selection since this was the mouse I first learned to use at least 30 years ago in the Air Force. Those trackballs looked like small bowling balls.

Easy to use. Great when sitting on the couch. Bluetooth. Connects every time.

#1 feature I love: My work from home setup has me using a MacBook (for work) and my own Windows PC. I connected it to the MacBook via Bluetooth and to the PC via the USB receiver. To switch the mouse from controlling one to the other, I simply press the button under the wheel. No more having two mice on the desk! Worth the price because it's two mice in one. (btw, the same thing will work with two PCs or two Macs--connect one via BT and the other via the USB receiver) Next up, I need to get the MX keyboard because it has the same feature.

This wireless trackball mouse works great. I love the ergonomics of the trackball and the wireless connection is a plus.

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.

Extremely accurate with a "fine focus" switch for more precise clicking, long battery life (USB rechargeable). Ergonomically comfortable.

Easy to use. It does minimize wrist movement. Better than regular mouse. Minor adjustment to using thumb to move around versus wrist.

As an Engineer, I exclusively use trackballs for my design programs. This trackball is comfortable, adjustable, and feature rich.

Not a big fan of mice, start a big truck ball person. I really like the strike ball very ergonomic, and I love the tilt. Super responsive

Best mouse I’ve ever had! Great for multi-machine use. Very easy on hands and helps to survive long days of working, especially if you have multi-monitor setup (or 49” screen) with a lot of estate to navigate between. The ball is the savior. Plus, you can set up hot keys on the additional ones and that is helpful too. It takes a day to get used to it, especially after a Magic Mouse, but does the hand enjoy this mouse! Also, easy to clean the ball.

This is a comfortable device that has a dongle to plug into your device's USB port. Works very well, easy to use. Battery lasts a long time too. Great tool!
