Kensington TB550 Wireless Trackball Mouse, Thumb Operated, Rechargeable, Ergonomic Design (K72196WW), Black

Great product, great price. I use it everyday! Plus it is programmable, and I love how the ball housing has a push button that pops out the ball for cleaning. The different DPI button is awesome as well depending on how precise you are needing the mouse movement to be. Customer service is excellent. I’m very big on customer service support. It connects easily with either the dongle connection or Bluetooth connection. You are able to connect to 3 devices using the 2 Bluetooth and the one dongle. One mouse for 3 devices. It has a fantastic battery life. I can use my rechargeable batteries with it! So far it is still going strong off of the first charge on my battery. I do turn it off when not using it because my lovely cat likes to walk across my desk lol The smooth roll of the ball is probably the best feature though. Slight movement is all that’s needed, especially if you’re using it on a higher DPI setting. I have yet to find a downside. The ergonomic design is very helpful when it comes to my carpal tunnel, I experienced less pain and fatigue in my hand. Love this mouse! Yes, I’m a real customer who just loves this great working trackball mouse.

I was using a Magic Mouse with my Mac and found it wanting. I think the QC is dropping off in Apple accessories. Had a good experience with a relatively cheap track ball mouse; probably Chinese, but when I installed my new Mac Mini M4, I lost my old Chinese trackball mouse and reverted to the Apple Magic Mouse. After a few days of frustration, I looked for a relatively inexpensive trackball and settled on the Kensington TB450 Wireless Trackball Mouse. It was one of my better decisions. It is top quality and very responsive and easy to use. It is also very comfortable as well. I highly recommend it. Maybe the more expensive ones are better, but this Kensington is a good value.

I’ve been using the mouse for a little while now, and it’s honestly a great little mouse. Super lightweight and comfortable. Track ball is on point. Pros: • Ergonomic and Easy to Use: It fits really nicely in the hand and has a smooth, ergonomic shape that makes it easy to use for long periods. My wrist doesn’t feel strained even after hours of clicking around. • Very Lightweight: I was surprised by how light it is, which is great for portability but still feels solid—not cheap or flimsy. • Stable Bluetooth Connection: The Bluetooth connection has been really reliable. It pairs quickly and I haven’t had any issues with lag or random disconnects. Cons: • Not a Lot of Extras: It doesn’t have any fancy customizable buttons or features, so if you’re into that kind of thing, this might feel a bit basic. That said, it’s definitely designed with medium-sized hands in mind. It might feel a little large if you prefer ultra-compact mice, but for most people, it should be a great fit. Overall, it’s a solid choice if you want a simple, lightweight, and dependable Bluetooth mouse. Definitely happy with it so far!

I'd been a Logitech user for 40 years. Their design and quality have been declining for a long time. As a longtime user of trackball devices, which I used in CAD for most of those years, their earlier devices saved a lot of movement and muscle, and lasted a long time. In recent years I was finding myself suffering from carpel tunnel and replacing devices twice a year. So, I decided to give this Kensington device a try. I noticed within days that the carpel symptoms disappeared. And the ease of use was a blessing. I also noticed a better quality of manufacturing that I'm hoping translates to longer life. No seams in the well that the ball sits in should translate to less jamming situations that the Logitech displayed. Well done Kensington!

Pros: 1. The contours on the trackball feel very comfortable in the hand. 2. The ball itself moves smoothly 3. The button at the bottom to pop out the ball for cleaning is a very welcomed feature. Cons: 1. The scroll wheel is the worst I have every used on any peripheral. Regardless of settings, it is simply not usable for normal work. 2. The button for switching connections between dongle and two BT devices cannot be remapped. Like me, I am guessing the majority of users will have the trackball on a desk connected to a single device. Not allowing for the remapping of this button makes it a lost button completely in most cases.

I love this trackball for work. The ability to move the cursor without having to slide the whole mouse across my desk has been a game changer. Just rolling the ball lets me navigate quickly and precisely, and I can get a lot done without repositioning my hand constantly. So far it’s been amazingly responsive, smooth, and comfortable for long periods of use. If you want a reliable option that boosts efficiency and cuts down on repetitive reaching, this is a great choice. Battery life is great, very durable and value for your money for sure. I work from home and it has been the best thing.

Terrible mouse, stopped working reliably within weeks. Cleaned everything repeatedly and nothing helped. I finally tried the ball from my old logitech mouse and it worked ok for a couple months, but now it's doing the same thing where it is unreliable and cleaning doesn't help. Hugely disappointed. Besides that, it feels cheap, and one of the most prominent buttons on the face of the mouse can only be used to cycle through devices, which is worthless and annoying since it's front and center and easy to accidentally click. Could have used that button for literally anything else, and even the software can't change its functionality. The big ball eject button on the bottom is great, but since cleaning doesn't improve anything it is ultimately irrelevant.

I needed a new trackball mouse after my old one of many years finally bit the dust. I didn’t want to shell out the cash for a Logitech one, I just needed something basic. Amazon had numerous listings, but this one ticked all the boxes. It’s Bluetooth, so no need to use up a USB port with a dongle. It’s Kensington, which has been reputable brand for the last ~20 years. It’s got a scroll wheel as well as the trackball, so easy to just use for online activity. And the best feature of all… it sounds small but it really does come in handy… is the patent-pending “ball eject button”. I think it’s just a plastic button on the bottom attached to a little spring-rod mechanism, so it’s not that high-tech. But it does exactly what it’s supposed to, and it makes cleaning those three little “helper balls” where the trackball sits, a real breeze.

Il y a mieux, je ne parviens pas à configurer avec le Bluetooth de mon pc 💻

This trackball ergonomic shape, is just right. I've used it now for several days and it meets all of my requirements. I find it much superior to an standard mouse. Recommended

Have always used another companies product, tried this one based on reviews and a lower price. Took a day to get used to the slightly different feel, now I'm very happy with. Great thumb ball mouse.
