Logitech ERGO M575 Wireless Trackball, Graphite

Easy to operate. I trust Logitech products to last a long time.

Good buy. works fine. doesnt mix signals eith other devices using the same logi brand. which was my eorry since the desks were nearby.

I've been using a track ball for years only Logitech. they're great and this one is Bluetooth so set up was super easy

Easy to put together and to use. Wonderful if you have arthritic hands.

the only problem is , you have to make sure it is compatible with your keyboard

Good product for a good price and delivery was very fast.

I absolutely adore this mouse. I have a lot of joint issues and it saves me so much pain!

I like this track ball, but I wish it had an internal battery that could be recharged

Good news, bad news. Let's get the bad news out of the way, so we can move onto the good news. First, if you're looking for a more virtual ergonomic mouse, this is not it. This is not the kind of mouse you can rest your hand on, either, as the smallest bit of weight will cause the right mouse button to click. The forward and back buttons, not on the side, but integrated into the left click button (they carve out a nook for them, on the left button). It is very easy to press these without trying. The ball is not as easy to control in gaming, so if you need to spin around real quick, this is not the mouse for you. Now the good news. The ball is very responsive and easy to control on your desktop and office suite. This makes it great for pint pointing the smallest pixel. You have the choice of both wireless via 2 GHz signal or Bluetooth, which makes it perfect for you to decide which works best (great if you have more than one device). I use rechargeable batteries and have yet to need to charge the batter.

The track ball on the mouse is not steady. Ball moves too much. All in all it keeps my hand steady. It does the job I need it to do except when it comes to pinpointing the cursor.
