Actual Color

Black/Blue Ball

Off-White

Simple to install and operate in various settings.

Reduces strain on wrists with vertical orientation.

Connection established via bluetooth or usb.

Buttons are positioned for easy accessibility.

I have used this type of pointing device for many years. For me, it completely eliminates wrist strain. It can be used on any surface, including your knee, while on a flight. It also allows for more precise control and has additional buttons that can be customized. There may be a learning curve but  it was well worth it for me.

A superior pointing device

Logitech

I made the switch to this ball mouse, it took a few days but now I love it. People said it was big but I think its just one finger too narrow in the width and that the LR buttons are too long(close to the palm). I'd like to palm the mouse more but it feels good still and is noticeably better for my arm, also Im faster and more precise now that I'm familiar with it.

Good Ball Mouse

Got this for the trackball 
But was VERY SURPRISED at how silent it was
Clicks are almost non-existent 
More quiet than a "silent mouse" I have from Logitech
They have been improving drastically

Stealth Silent!

This is my first time using a stationary mouse, which means you don't move it around like the other ones, at first, it was a little weird using your thumb for movement but it's all good 
everything is smooth, quick, and quiet, you don't hear any clicking and has a fast response especially when gaming,

smooth, quick, and quiet

walmart.com

Most comfortable trackball you can find. Used the trackman marble plus when I was younger, this is even better! Only comment from me is the click buttons are kind of easy to push and I accidentally clicked for a while when I first got it, but they truly are silent.

Best trackball you can buy

I really want to like this trackball. In fact, compared to my mouse, well, any mouse, really, it's a definite step up. The main issue I have with it seems to be personal. Not having used a trackball for years, I was expecting the ball to have a measure of resistance. Rather, it's very fluid, but my thumb is so shaky that I can't pinpoint anything without dropping to extreme precision mode. So I use my trackball, "Off label"; i.e. not as intended. So, now, I use my thumb and forefinger for rolling and precision, and mid and ring fingers for clicking. Works. Weird. But no strain whatsoever. This I like. Not quite a fiver, tho.

Off Label Use

Like the features and functionality.  I don't really want to download an app to adjust the settings, would rather download a driver

Call me old school

Logitech is my go-to PC accessory provider because they deliver good design and durability at a reasonable price.  These are the primary reasons that I've used Ergo series trackballs for long enough that my first units were corded.

Nice design, sturdy and a good value

The ball does not roll smoothly. many times I would lose my site. was quite annoying .logitech offered a software to help, but I could not download it -frustrating!

not for me

Very uncomfortable to use. My wrist was hurting immediately and, after using for a while, my arm hurt up to my elbow. Put it away the very first day and went back to using my Anker (which has problem with batteries).

Not for me.

Logitech ERGO M575S Wireless Ergonomic Trackball Mouse for PC/Mac in off-white with a sculpted ergonomic shape, featuring a large blue thumb-controlled trackball, two side buttons, and a scroll wheel, designed for reduced forearm strain and precise cursor control, suitable for compact workspaces.
