[Mac, Windows] I have been a Kensington Expert Mouse Trackball customer for decades, but up to now have only used the wired version. I wanted the wireless version for when I'm away from home. I use it with a 16 MacBook Pro and prefer something besides the built-in trackpad for moving the cursor around and scrolling chores. When I'm at home, I have the MBP plugged into a dock that has a Kensington Wired Expert Mouse connected. I'm very happy with the wireless version. Works as well for me as the wired ones at home. I use the Bluetooth connection option, not the dongle. No issues to report. Yes, the trackball is somewhat bulky, but there's plenty of room for it in my backpack. I'd recommend it!

[2] Upgrading from the USB wired version. The wireless one seems to work just the same, which means its great.

As of 2023, on a 2019 MBP running Monterey OS, the Kensington app is useable with Bluetooth. The dongle is NOT required to use the app on my setup. Quite pleased with this.

There is no noticeable latency for me when using the mouse for precise photo-editing or general internet surfing. Be sure to use the app to set up sensitivity to your liking, just like any other mouse.

[Ambidextrous] [This review was collected as part of a promotion.] I have used a trackball mouse for years, this is my first wireless trackball and I love it.

[Mac, Windows] First one I got stopped working after 4 years of use. Fell a couple of times though. Everything worked except rhe ball itself.
Didn't hesitate to order another one. Solid product, prompt and professional service from B&H

[2] For many years I have used the corded version of Kensington Trackball. Now is the time to make the switch to Wireless!

[2] After years of using the Kensington wired series at home and the wireless on the road, I decided to switch to the wireless expert trackball at home. It switches seamlessly between my multiple machines with the smooth tracking and scrolling I have come to expect from Kensington. Great product.

[Ambidextrous] My old wireless trackball wore out and it's not made anymore. A lot of trackballs use a really small ball, which isn't very accurate when you're selecting single pixels and such. This also has really good, simple software for setting up the buttons and fine tuning the pointer and scrolling. I don't know why anyone would want to use a mouse.

[USB-A ] My favorite mouse.

[Yes] I have been using a Kensington mouse for many, many, years, one that is exactly like this one, but not wireless. My wired one still works great, but but UI wanted to try their wireless, and this mouse is just as nice as the wired one, but without the hassle of the wire. I would highly recommend this to any one, it is one of the finest mouse you will ever find.

[2] This is not my first Kensington track roller - I LOVE them. Great ergonomic set-up. takes a little getting used to, but then so good for your mousing hand.


The newest version throws me off a bit as it puts itself into deep sleep so each morning I have to remember to flip it over and turn it on again, but that is better for battery life.
