We bought this for our adult son who is terminally ill ad has minimal function in his fingers and this works perfect.

Was looking for something different then my traditional mouse for work. Like all Logitech products it works great!

This mouse is great! Got it for my fiance and it really helps with ergonomics. Since he's an audio engineer, he's constantly on his laptop, normally, his fingers would cramp. Now he can comfortably, rest his hands on this mouse and use the ball to scroll around. I'm going to buy one for myself next.

This mouse works perfect for when you want to be rid of the cord chaos. very easy on the hand. I am still getting to know all of the buttons. Haven't tried the Bluetooth, just the usb connection because nI have several other things connected. The usb has its moments when it lags especially if you have extended screens with your computer.

It took me a little while to get used to it, but I love it now. It's much more convenient than a normal mouse.

I prefer this model to the more expensive Ergo. I like the AA battery, rather than a rechargeable.

I am using a trackball mouse for the first time, but I bought this so I could use a mouse while sitting on a sofa with my laptop. no need for movement of mouse. I'm still gaining the dexterity to use this mouse well, but all in time. My hardest task is highlighting a URL to copy and paste.

The M570 Wireless Trackball Mouse has been my number one choice for several years. I use it for my desktop and two laptops (own three, one for each computer). The thumb ball control is not hard to get used to, and the mouse is stationary so can be set on just about any surface.

I've been using this thumb trackball mouse since they first introduced its predecessor because it takes up less desk real estate and is far more comfortable to use for extended periods than any traditional mouse I've yet seen or tried.

I was specifically looking for a trackball mouse to relieve tendonitis in my elbow. Normal mice use an unnatural hand position that stresses the main tendon in the arm. The trackball mouse allows your hand to assume a more natural position, with thumb oriented upwards. Frankly, I think I have more control using my thumb to control the cursor than my whole hand. The trackball mouse is wireless, and appears to have good performance.

I hate regular "mouses" and TouchPads. With a regular mouse my wrist hurts. I have used this kind of mouse for years. The thumb/index/middle finger combination is great for me. I have one for work and one for home. I have given these as gifts.

Only issue is that tracking ball needs cleaning frequently as it disrupts movement when dusty or dirty. Other than that very happy with it.

I first used this mouse when the occupational nurse in my office recommended it to relieve my carpal tunnel and arthritis pain. It has provided a lot of relief considering I am on the computer for average of 10-12 hours a day. I have even bought this product for my home use, travel use and for my sister.

I love this mouse. I've been using this exact mouse for years. I have two and I just got this one for my mother. I like these because (1) they are better for your wrist, (2) you do not need a mousepad (3) you can use them on any surface (4) they are a must if you have a multiple monitor setup (so you can whip the mouse across the monitors)... I leave one on my desk, and the second one I leave upstairs when I bring my laptop upstairs. Unlike the traditional mouse, You can put this on the couch, on a glass table, on your leg... etc. and it always works exactly the same. Every few months just use your pinky finger to pop the ball out and then use your finger to wipe out any lint that is inside the housing. The lint causes the mouse to move slower on the screen. Hope this was helpful. I would never go back to a regular mouse... :) but that's just me. :)

Love this mouse but they don't last very long. I find myself replacing it every year or so. Maybe less. The trackball starts to get hard to move and I'm constantly having to remove the trackball and clean it. But it's great for photographers and videographers. The trackball helps alleviate some fatigue from using the computer too much.

A great mouse for the buy, I have owned 3 of these, desktop, laptop and at work it has held up over the years

Why didn't I get it earlier!!!! I love this track ball mouse. Its easy to use and I adjusted quickly. There were a few days where I kept trying to move the whole thing around. Anyhow I love it its great and affordable!

I purchased this to use with my laptop because I do not like using the trackpad. This works great!

I have used this style mouse for 25 years now. Each time I had to replace it for some reason, I go out and buy the same one. I love using my thumb to navigate as I've gotten so used to it.

Only bad thing is they don't communicate off one USB. They require two ports for the two separate devices. Other than that, they're awesome!
