Customer Ratings & Reviews

I have two computers on my desk. I bought two M570s and they work great. No wires, no mess

Tracking balls are better than mice for me because there is no friction on my palm. Love this wireless version; less clutter!

Purchased this item for a friend who suffers from carpel tunnel from using the mouse. It seems to have fixed the problem.

I like the track ball because it allows me to use minimal space on my desk as I play games and surf the web

I love this mouse - I use it at home and work, so much easier for me than the small movements required for a regular mouse.

Been using this for some time now and just bought another one, can mouse all day and no wrist pain, I have carpal in both hands

My wife uses this because of a shoulder injury. It lasts 3 years between breaking with 8+ hour daily use. Highly reccomend.

Best mouse I've had, so easy to use, my thumb controls the track ball so easy. Don't need to move the mouse all over the place, the ergonomic for for the hand is confortable. The Bluetooth connection is instant when I turn on the computer.

This is the third of these trackballs I have bought - not because one broke, but to have one at home, one at work, and carry one with my laptop when I travel on service calls. Plus I like the receiver I have for my wireless keyboards at home and at work readily sync to these - so I don't need 2 receivers in the PC. I initially bought the first one because I really am not comfortable or 'fluid' using a mouse - and for the laptop I despise touchpads.

Great ergonomics for long day's at the office or on the go. Traveling a lot this trackball mouse is easy to take with you as there is no wires to wrap up and tuck away in your bag. Just pop the trackball on any surface and your good to go. And with the USB receiver included you can easily share. I have 3 of them - home, office, and on the road.

this is easy on my hand for it gets tired easily with other mice the tracball is good for folks with minor hand problems.

I work in excel on large spreadsheets between two screens. I wanted the trackball for ease is scrolling. It's been great.

I like using the trackball with my laptop computer while not at a desk. The kids prefer the traditional mouse while gaming. It would be nice if the mouse automatically paired with the keyboard dongle.

I've been using a trackball for a while now instead of the standard mouse. This fits my hand perfectly and the price is reasonable. The only negative I see about this trackball is the short range of the wireless connection. You have to keep it close to the receiver for it to work properly, not an issue to me though.

Why didn't I buy one of these a long time ago?! Very smooth and no more moving your mouse back and forth!

This mouse is easy to use. I have been using more than 2 years. Works great. No issues. Track balls helps to avoid moving mouse. I would highly recommend this. Definitely good for multiple monitors where you have to keep moving to different screens.

Got this to go with my laptop and it works great. Very comfortable to use and track ball is very smooth.

I have tendinitis in my wrist so a trackball is a must for me. I have tried several and so far this ones my favorite. The fact it’s wireless makes it superior to most. I’ve used for a while now with no issues. Haven’t had to change the battery yet so not sure the lifespan but it’s long.

I currently use it on a fairly new PC laptop, and a very old Mac Pro. There was no conflict after installing the Bluetooth USB plug in my Mac USB keyboard. Since my Mac is very old, there were no fine-tuning settings, but it appears to work just fine. It's also nice that the right-click button does the same thing as a Cntrl-click combo the single button the Mac utilizes. The PC side is also working well, since I hate the trackpad that most laptops possess. The mouse is AA alkaline battery-powered (coming with one already in the package). The mousewheel does its job in scrolling webpages or adjusting the 3D enviroment in Solidworks. This trackball mouse would be perfect, if I had a slightly smaller hand to manipulate the trackball and have a comfortable stance above the mouse keys. The trackball does occasionally stick, which may be an issue if you require some accuracy (I wouldn't paint with it or do Photoshop retouching with it), but I wouldn't use a regular drag and click mouse like that, either. The plastic is lightweight, but not flimsy. The buttons give a solid click and the page up/down keys do the job on the PC laptop, but default as a command-tab switch to other apps on my Mac (which I believe I could manipulate with the proper driver).

Love the design and functionality of this trackball. I have a stand/sit desk and this was a welcome addition to the setup as there wasn't a lot of space to move a regular mouse. The built-in capability and the additional button makes this a very welcomed addition.
