Logitech Trackball Bluetooth Receiver

I was disappointed to learn that logitech had discontinued the M570 trackball, but the M575 is even better. It has built-in bluetooth or dongle (usb) connectivity.

My main desktop machine is old enough not to have had bluetooth available. This device allows me to use my Logitech keyboard and trackball, and stream music all at the same time.

Nice build quality, on/off button, yes it works with the Bolt receiver or Bluetooth. The entire top comes off for easy cleaning. The round circle can be assigned. This uses Logitech Options. Logitech price is expensive. Logitech should offer an Ergo version.

I tried several mice and trackballs including logitech M570 and the Trackball Marble. This trackball by far is the best for CAD. The ball movement is so precise, fast and smooth. The stroll ring could be better, but it's not so essential to my work. Highly recommended.

Very good Bluetooth receiver.

Needed a lightweight trackball with Bluetooth. This fit the bill and so far works flawlessly.

I have always used a trackball and have been waiting for a wireless version to come out. This works great either through Bluetooth or USB.

I am so grateful to have found the Kensington Trackball. I bought it to replace two Logitech trackballs that I had previously owned (the M570 and the Ergo M575). I had to go online to find the Kensington because all of our local stores only carry Logitech. The Kensington is brilliant. Once you learn how to customize the trackball using Kensington's software, it's easy to find the most comfortable angle for your wrist. The Kensington is solid and heavy, which I like. It stays in place on your desktop. The USB dongle connects the mouse without disruption. And I like the scroll wheel. The Kensington itself is more intuitive to use than you would think, and (hopefully) it will last a long time. It comes with a manufacturer 3-year warranty, which is the longest manufacturer warranty that I have seen on trackball mice of any brand. This mouse is definitely worth the price. I take online classes and write computer programs, so this trackball mouse helps a lot with relieving wrist and forearm pain. It's worth the investment. It takes a few days to get used to it, but once you do, it's doubtful that you will go back to other mice, trackpads, and such.

I've always used a trackball over a mouse. No need for extensive desk real estate. This is my second Orbit, one on home desktop and one on work desktop, both of which replaced Logitech Trackman trackballs. The Logitech was good but no scroll ring. I also have two Kensington Expert Mouse trackballs on editing machines. These are the best but a little pricey. The Kensington Trackball Works software also makes it easy to customize your user preferences and responsiveness.

I've been using Kensington trackballs for about 16 years. I forget what they called the with one with the wheels but that was my first. I moved to expert mouse when optical technology came out. I still use an Expert Mouse wireless, an Expert Mouse, and now this SlimBlade. Believe me folks NOBODY makes a trackball as smooth as Kensington. I got this SlimBlade to use with my HP laptop because I just couldn't stand the products offered by Microsoft and Logitech. The SlimBlade has a unique way of scrolling by twisting the ball and after two weeks I see the death of the scroll wheel on the horizon - it's that intuitive. If you want a trackball save the money you'll waste on a MS or Logitech ball and pay the few dollars more for the Kensington. You won't go back.
