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 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

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

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

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 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.

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.

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.

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

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.

Easy to use, the buttons are right where they should be. The software is easy to install and makes customization a breeze.

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.

I love my trackball. I never have to chase it around my desk to move the cursor. Being wireless just makes it even better.
