KensingtonSlimBlade™ Pro Wireless Trackball, Rechargeable Battery, Bluetooth 2.4GHz Connection Options (K72080WW)

In a world dominated by standard mice, the Kensington Trackball Mouse offers a refreshing — and highly functional — alternative. Designed for users seeking precision, comfort, and space efficiency, Kensington’s line of trackball mice (particularly the Expert Mouse and SlimBlade models) has earned a strong reputation among graphic designers, video editors, accessibility users, and anyone looking to reduce wrist strain. After several weeks of use, I can confidently say this mouse is more than a niche tool — it’s a productivity powerhouse.Ergonomic Design & ComfortThe most immediate difference is how you interact with the device. Unlike a traditional mouse, the Kensington trackball stays stationary. You control the cursor by rolling the ball with your fingers or palm. This design is a huge win for ergonomics — it eliminates constant wrist and arm movement, reducing the risk of repetitive strain injuries (RSIs), especially during long work sessions.The included wrist rest (on models like the Expert Mouse) adds another layer of comfort. It’s soft, detachable, and encourages a neutral hand posture. Over extended use, I noticed significantly less tension in my forearm and shoulder compared to using a regular mouse.Precision & ControlThe large, smooth-rolling ball is surprisingly accurate. Once you get used to the motion (which takes about a day or two), fine control becomes second nature. Whether you’re navigating through spreadsheets, editing photos, or simply browsing the web, the trackball allows for quick, pixel-level precision — especially useful for design work.Customizability is another standout. The KensingtonWorks software lets you program each of the buttons (typically four on the Expert Mouse) to suit your workflow — from copy/paste shortcuts to opening apps or executing macros. Scroll ring functionality is also intuitive and surprisingly satisfying. Rotating the ring around the ball allows for fluid, smooth scrolling that quickly becomes second nature.Build Quality & DurabilityKensington devices are built like tanks. The materials feel premium, with a sturdy plastic body, high-quality ball bearings, and tactile buttons that hold up well under daily use. Unlike many traditional mice that begin to degrade after a year or two, a Kensington trackball can last years with minimal maintenance — just an occasional cleaning of the ball and socket.Learning CurveThere is a brief adjustment period if you’ve never used a trackball before. It may feel awkward initially, but within a few days, most users adapt quickly. The payoff is worth it — less movement, better posture, and surprisingly faster navigation once you’re accustomed to the motion.Final ThoughtsThe Kensington Trackball Mouse isn’t just an alternative pointing device — it’s a serious upgrade in terms of comfort, control, and customization. Whether you're managing multi-monitor setups, working long hours at a desk, or dealing with wrist issues, this mouse delivers reliable performance with thoughtful design.Rating: 5/5 – Ergonomic, precise, and built to last. An excellent investment for professionals and power users alike.

I've used variations of the original Kensington Smart Mouse (trackball) since the mid-90s and have been hesitant to make the change to this model because of the change in the scrolling mechanism compared to the current Expert Mouse, with a mechanical scroll ring. I did not know if I could adapt or would like the change, but I immediately found the SlimBlade intuitive, and it had even better performance than the old scroll ring. My biggest fears were dispelled.Overall, it is quite an improvement over the older Expert Mouse (trackball).This trackball can be directly connected to the computer, and the cable is a standard USB-C variety. I have two old cabled trackballs in the junk drawer due to cable shorts. I also have a couple of the older versions with the dongle that are worn out, too. I preferred the dongle version in the older Expert Mouse, but they went through batteries and did not always work correctly. I was excited to read that the SlimBlade can last months on a single charge using the dongle, so it is like the best of both worlds.The construction of the SlimBlade is a big improvement over the old Smart Mouse. It is sleek and less prone to clogging, which was a constant cat-hair problem in the past. To me, the buttons are easier to click, and it is much quieter. One of the things I notice most is that it is less bulky than my old favorite, the Kensington Smart Mouse; it is a pleasure to use.

Would be 5/5 if it weren't for some QC issues. I've purchased 3. Had to return 2 because of issues with the mouse button. One was way too hard to press, the other would press down but not activate.

I am a huge trackball user , insofar have used only thumb trackballs, this is the finger trackball I've used and I love it.I use Linux almost exclusively so a bit of customizing is required to get the buttons to work as desired.In terms of precision, there are 4 settings i prefer the 1200 setting.Straight out of the box the buttons function as follows:2 81 31= Left Click2 = Middle click3 = Right click8= BackI had to remap it so that i had both Back and Forward functions activated.The other thing I noticed is that the ball is much heavier and stays in position purely by gravity. If you turn it upside down it will fall out.There are 3 connectivity modes, USD , Wired and Bluetooth, I connected the BT and upon boot , it connects without issue saving a USB slot.in terms of cons , the one problem is the button clicks are pretty loud. Not a big deal, but perhaps on the next iteration Kensington can fix that.Scrolling: Another unique feature is the scrolling is done by rotating the ball on its x axis .It takes a bit of time to get used to, but once you get the hang of it it's fantastic. I use my index as the pivot on the top and then use my middle finger to rotate the ball. Very easy and very accurate.

Why did you pick this product vs others?:I’ve been a Kensington fan for years. I’ve always hoped for a wireless trackpad just like this. Now, even comes in white !
