Logitech - ERGO M575 S Wireless Ergonomic Trackball Mouse - Wireless - Black

Fantastic ergonomic mouse - my wrist feels better, it stays put on the desk, and the thumb trackball is far more precise than I expected. Perfect for small desks and long workdays, no more shoving a mouse around, just smooth thumb control and a super comfortable hand position. If you spend hours at computer this trackball is an easy upgrade. Minimal learning curve, great comfort and excellent wireless reliability.

This mouse is SUPER easy and comfortable to use - it is the best one that I have ever used!!

I've used the original m575, the MX Ergo S, and now this version of the m575. Especially now that it comes in white and has bluetooth, I can't stress enough how much you should go ahead and click "buy" right now. I honestly prefer this over the MX Ergo S, even with the extra features the Ergo has. The plastic is surprisingly very high quality, the buttons are tactile but quiet, and it just works! Looks even prettier in person.

This mouse is my favorite of all mice I have used! It is ergonomically correct and fits my hand perfectly, helping me to avoid repetitive stress injuries. You don't have to move the mouse or fight with a cord because it is cordless and stationary. The trackball is easy to use and is perfectly placed for your thumb. It has a scroll wheel to go up and down the page smoothly and the right and left buttons can be changed on the settings. I can't say enough positive thoughts about this mouse!

I loved the M570, I've used it for years, but unfortunately it's been discontinued for this M575S. While there is the new Logitech Bolt receiver, and Bluetooth, this trackball is unfortunately a downgrade. The trackball is not as smooth as the old mouse, and there is more friction, although it's easy to swap out the ball on this trackball for an old one or a 3rd party ball from Perixx. However what I can't really get over is that they've decreased the force required for both the right and left click buttons. It's so easy to accidentally click on this mouse. If the M570 was still available, I'd buy that, but unfortunately I have to make do with this. Logitech's quality really has gone down hill. They need to bring the micro-switches from the previous version back. No clue what the long term lifespan of this mouse is, but if the M570 I've had in the past was any telling, the left click will fail around the 12-15 months mark, however I haven't used this current version long enough to know how long it would last.
