Customer Ratings & Reviews

Live this new version of the original. The ball moves much better than the previous version.

Very good service and good product and friendly staff

I've used these for decades, though some of course were earlier versions. There is nothing better ergonomically, IMO. My previous one finally died and I tried using a mouse for a few weeks, thinking I'd adapt. I didn't; I hated it. I do appreciate the new white color. A tad high priced though, even with discount, for simple technology this old.

Trackball does what I ask it to do, it works well, suits my use well.

I have large hands and this is one of the best things I've found @ a reasonable price.

Great mouse wrist feel better using this . Quality mouse

It's comfortable, fast and smooth. It's the only mouse I've used for the last 12 years!

Good deal, excellent quality I’m happy with my purchase

Have carpal tunnel and began using this type of mouse a few years ago. Eases pain and really can't use any other type.

Love the new mouse. Much easier on my shoulder. Takes a few does to get used to.

Mouse is comfortable. Takes some getting used to. Does occasionally slide up.

Exactly what I wanted and it works great! I can't say it any better than that.

Have used Logitech Mouse for 20+ years. I have RSI diagnosed 1988. IT at my job got this for me. I immediately bought for home. My purchase today is because I dropped mouse & it didn’t survive. Replacement

use it 8hrs aday cant say more thanGREAT HAVE SENT 1 TO A NEISE

Excellent fit and finish. Would recommend for anyone who has wrist discomfort.

works as expected 5th in a long line of this style of mice

I didn't think it was possible for Logitech to take so many steps backwards on a new product revision, but they did so with the M575 and it primarily comes down to spacing. Let's start with with the placement of the back/forward button. Before, they were outside the left click button. It wasn't a perfect spot, but it wasn't horrible. The new system put the left button around the backwards and forward buttons. This leads to increased miss clicks when going forwards/backwards on pages or double button clicks when using one of the most important buttons on your mouse. The mouse buttons are also spongy. There is no firm click action to prevent accident clicks while your fingers rest. Small amount of pressure will set off the actuator and these small pressures are common when you also notice they removed a finger rest spot. On previous revisions, there was space for two fingers to be on the right side of the device, cradled off the ground. Now this space has been slimmed down to just one finger space. This leaves you trying to fit three fingers in a cramped button area or leaving one finger on the table, neither of which is a good option. Lastly, a none ergo gripe, but there is no DPI switch to control the trackball speed on the mouse. If you want to control how faster your cursor moves, you must download a separate program from Logitech, clocking in and around 200MB. If you don't plan on remapping buttons for other Logitech products, then that entire program will only do one function for you and must be installed on any machine you plan on using the trackball.

It's fine. It seems to work, my last one died after 2 years but I can't find one that fits as well.

easy and relaxing to use, fast setup and fun to use over old mouse
