Kensington TB450 Wireless Trackball Mouse, Bluetooth LE & 2.4GHz Connection, 4 DPI Options, Connect up to 3 Devices (K72194WW), Black-Blue

Kensington makes great trackball mice. I own two Experts. But I needed the thumb-ball for travel and sitting on the couch. The best thing about the mouse is that it supports several devices whether wireless 2.4 or bluetooth.I like the elongated design which is confortable for browsing Amazon and like sites. For the on-sale price it's worth it while you can get it. Compared to like devices, it's easier to use and clean. Money well spent. The mouse is great for gaming as well. Thumb based trackballs were the secret sauce for FPS games but also RTS.

I purchased this November of 2023. Unlike other mice that I have purchased, it still works and works good. I use it in my living room with my Steam Link and have never had connection problems. It is really easy on batteries. I use this mouse almost everyday and have only used about two or three batteries in over a year. I would recommend this product.

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 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.

The media could not be loaded. The mouse feels really good and the hand. I have large hands so the fit is perfect. The buttons are in perfect position. The connectivity options between Wi-Fi and Bluetooth are definitely a plus. However, the actual track ball itself was a little bit too “sticky” for my preference. I have an older track ball mouse with bigger ball that doesn’t have this issue. I was hoping for the same here. The overall belt quality is great. It’s plastic but not a cheap plastic. It is definitely a high-quality build. I just wish they fixed the wheel issue.

Works like a champ! Connects easily and kicked in simply. I bought this to replace the Nuela Bluetooth - which connected intermittently and was always giving me problems.

Super smooth and easy to clean.It has helped me to reduce my wrist pain, it's comfortable andcomes in good size.

I've been using the Logitech wireless trackball mouse for several years now. I still very much like them, but I wanted a trackball that has a few more features: 1) sideways tracking 2) USB-C recharging and a 3) slightly larger footprint. This one was supposed fit that bill, and for about 3 days, it did. And then.....-The cursor started getting very "jittery" after about an hour of use. I thought my OS was acting up. Turns out, the built in battery was almost fully discharged. Hmmm. No bueno. I plug in the charging cable, and voila, works like a charm. So, it's now been a wired mouse.-The trackball initially was silky smooth in its rolling performance... well, that lasted about 3 days. It has slowly getting more and more difficult to roll. I've cleaned the bearings several times. I've tried the dry silicone suited for plastic electronics, and while it helped initially (a little), it's now as bad as ever. To the point I've simply gone back to my 4 year old logictech mouse. This isn't the first kensington office product I've used, but it certainly is the worst.(I would have returned it within the 30 day window, but alas, extended work trips are a thing.) I am reaching out directly to kensington to see what they say. I'll follow up on this review once finality is reached.
