KensingtonSlimBlade Pro Bluetooth Wireless Rechargable Ergonomic Trackball Mouse for Windows and macOS, Ambidextrous Design and Optical Tracking (K72080WW)

The 3 fold connection ability is really useful. I can Bluetooth it to my main computer or USB dongle it to any other (or tethered USB when the battery needs charging). It seems well made with a high-quality charging lead. The only thing you have to be careful of is that the ball is not captive so if moving it you need to make sure the ball doesn't fall out. However, this also makes the ball and sensors easy to clean.Unlike traditional ball-type devices with roller sensors, this unit has a pair of optical sensors like an optical mouse to determine motion. They seem to work well and should be easier to keep fluff and dirt away from.As a finger (rather than thumb) operated ball I think its hard to beat. One oddity is that the instructions give details on how to disassemble the unit in order to change the battery and then state that the battery is not user replaceable! Go figure.

Finding this mouse and installing it (which was very easy) has been very liberating. I am 69 years old and suffer from Parkinson's, which effects the way I use keyboards and the mouse on my computer. I use the computer daily, for my work and find the Kensington Slimblade Pro has made a huge difference to my editing and navigation. It has been enlightening. I highly recommend it

Nice one but it didn't help me with relief of my hand. It was my aim.

A little weird to love a mouse but I have to say this mouse is brilliant. The price tag is by no means hefty even for an ergo mouse (to which I own a few). This mouse has solved the pain in my index finger (strained from overused) which my other ergo mouses could not resolve. The key was in customising the buttons so that I use the other fingers more instead of relying on my index finger. Double clicks can also be done in 1 click which means half the clicking. So glad I gave this a go. No price for happy fingers.

This is a fantastic trackball if you want to get more serious about ergonomics. It’s harder to get used to versus a thumb trackball like MX Ergo, but it’s well worth the effort.Build quality is kinda bad, glossy plastics and squeaky buttons. But the ball itself and the sensor is really good quality and makes up for the shortcomings.Using it on a Mac, I recommend purchasing the Steermouse app to adjust settings, it’s much better than the Kensington software.

Fast delivery, very well packaged and easy assembly. It works great!

I decided to give the Kensington SlimBlade Pro Bluetooth Trackball Mouse a try after hearing numerous recommendations about the benefits of trackball mice. Initially, I was quite impressed—the mouse felt comfortable, and the trackball was smooth and responsive, offering a different but enjoyable experience compared to a regular mouse.However, things took a strange turn on the second day. Out of nowhere, the trackball started feeling firm, and it wasn’t moving as smoothly as it did initially. Even more frustrating was the fact that the cursor began to jump erratically across the screen, making it difficult to use. I tried everything I could think of to fix the issue, including cleaning the trackball and reinstalling the software, but nothing seemed to work.This was a very unusual and disappointing experience, especially considering how well it worked on the first day. I ultimately had to initiate a return, which was unfortunate because I was genuinely excited about switching to a trackball. For now, I’m going back to my regular mouse, but I might give trackballs another chance in the future with a different model.

Initially I couldn’t justify the cost over using just a normal mouse for music production but I am so glad I eventually got this .No longer have to keep moving things on the desk to use the mouse . Put this in its place and it never has to move again.Also can configure the software so the buttons or a combination of buttons can do different things in different software.Got used to using it very quickly and now would never use a mouse again thru my own choice.I would replace this straight away if I needed to..
