## Description

Using a mouse may feel familiar, but it can also provide less-than-precise navigation, cramped desk space—and cramped hands. The Pro Fit® Ergo TB550 Trackball brings the comfort and convenience of trackball technology to users who want to improve wrist and forearm alignment or work in tight areas with limited desktop space. An ideal solution for people who want to try a trackball for the first time, it is made of 51% recycled plastic and includes long-life rechargeable battery, enhanced 4D scroll wheel, choice of Bluetooth® Low Energy (LE) and 2.4GHz wireless connection options for maximum flexibility, and patented ball ejection system for easy cleaning.

Review: Great product for a great price! - 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.
Review: An excellent value for a 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.

### ⭐⭐⭐⭐ Lightweight, Comfortable, and Reliable Bluetooth Mouse
*by A***O on May 25, 2025*

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!
