I really like this roller ball mouse, I just wish it held up better. They only last about 9 months to a year before they start having issues like double clicking or the scroll wheel doesn't work properly.

This is an upgrade over the original m570. The ball is noticeable smoother. The ability to connect to bluetooth is finally here. The scroll wheel is the feels the same, worse than the ergo trackball model

Spend many hours on computer with a mouse, this one gives relief on the forearm, wrist and shoulder. Rasy connect.

I have used roller ball for many years now and like it so much better than a standard mouse

Great trackball for all of the trackball type people out there. Easy to clean and will not let you down.

Always prefer track ball over mouse. Uses less space. This one is inexpensive, plug & play and ergonomic.

Bought this for my granddaughter. She has a challenge using a normal mouse. This works perfect for her.

I love logitech, this is a newer version of a wireless trackball and really love it.

I love the ball mouse. Hand and wrist fatigue is virtually gone. Much quicker on the screen. Awesome.

I had one of these 'mice' for a few years and totally loved it! I've used them for a long time. In fact, I went through a couple of them. I had to give them up though because as my age was catching up and the arthritis in my thumb became more painful. I dealt with it for awhile. I didn't want to give up my mouse. But when it dawned on me, that might be aggravating my problem ... I had to give it up. But these are great! I loved my mouse staying in one place ...

Bought this item because I have nerve damage and regular mouses are painful to use. This mouse is so comfortable and is effortless in it's use. I would highly recommend this to anyone who suffers hand issues such as carpal tunnel or nerve damage.

Smooth rollerball. Easy to use . Perfect for anyone having problems with wrist or arm.

Absolutely love this mouse, used to use a similar model as a kid ... So it took sometime to get used to again, but it is a huge help with a smaller area and great for the wrist.

Great product, easy to use. Great price and available in the store the day I needed it.

If you do photography and editing or design, this product is awesome. It is stationary and has consistent movementand connected easily to my apple computer.

If you have ever had carpal tunnel, this is the mouse for you! I had it so bad I had both wrist braces on full time. Changing to this + the Microsoft Natural keyboard was a lifesaver. If you've never used a trackball, it will take several days to get used to, but once you do, you will never go back! The last model of this I had for so long that it stopped work even after tearing it apart, cleaning & adjusting it. This new model has a perfect fit to my hand and the 5 buttons (yes even the roller wheel can be clicked) can be mapped to do anything!

This is the best mouse and it’s so easy to use. I wouldn’t use anything else

This is a great mouse. Love the way it feels in the hand, very easy to use with your thumb on the ball. I need to replace mine as the covering on the scroll has been worn away. This will be the 4th one I've bought.

This was a replacement for an older verison. The new one works as well as the older model i had used for years. I would recommended this model for anyone wanting to use this type of mouse.

Works well so far and is comfortable to use even with carpal tunnel. Took some getting used to using the forward and back buttons being right next to the left click key. Would like to see better grips for the feet since I tend to have it slide across my desk while using it.
