Our Testing Experience
First Impressions
When I first unboxed the ProtoArc Wireless Trackball Mouse, I was immediately curious about its unique design. The adjustable hinge caught my eye right away because I like to customize my workspace for comfort. Setting it up was simple—just a quick Bluetooth connection to my laptop, and I was ready to go. The mouse felt solid and well-built, and the gray ball had a smooth finish that invited me to start using it. I was excited to see how this thumb-controlled trackball would change my usual mouse routine.
Daily Use
Using the trackball mouse every day quickly became a habit. Instead of moving my whole arm, I just rolled the thumb ball to move the cursor, which felt surprisingly natural after a short adjustment. It was especially helpful when I was working in tight spaces like on my couch or a cluttered desk—no more awkward arm movements or trying to find more room for a traditional mouse. Switching between my laptop, desktop, and tablet was seamless thanks to the triple connection modes. It saved me time and kept me focused without fumbling with different devices.
Key Features in Action
The adjustable hinge was a game changer for me. Being able to tilt the mouse from 0 to 20 degrees meant I could find the perfect angle that felt comfortable for my wrist, reducing strain during long work sessions. The precise thumb ball made scrolling through documents and web pages smooth and easy, which really helped when I was editing or researching. Plus, the rechargeable battery meant I didn’t have to worry about constantly buying replacements, which is always a plus. The ability to switch between Bluetooth and 2.4G wireless made the connection stable whether I was close to my devices or a bit further away.
Long-Term Performance
After using the ProtoArc trackball mouse for several weeks, I noticed less fatigue in my wrist and arm, which was a huge relief. The build quality held up well, and the battery lasted longer than I expected between charges. The trackball remained smooth and responsive, showing no signs of wear or slowing down. Overall, it has become my go-to mouse for both work and casual browsing. I would recommend it to anyone looking for a comfortable and efficient mouse, especially if you spend a lot of time at your computer.
