Review: First trackball mouse, easy transition, excellent mouse - Updated - one year later. I bought this mouse for home use as well and couldn't be happier. I bought one for a co worker and she's a convert. I tried a different trackball mouse (uses your thumb instead of your index/middle finger) and found it was very tiring for my thumb. I also tried a "vertical" mouse; it worked ok but it wasn't as "natural" feeling nor did it give me as much relief as the Nuela does. The sensitivity of the track ball is adjustable, similar to how you would adjust the responsiveness of regular mouse; this makes a world of difference is usability. My only caveat is if you play FPS games. I occasionally play FPS games, and I can *mostly* use the Nuela mouse for them. When I play a FPS, I dig out my old "normal" wireless mouse and put it on my desk so I can quickly switch if I need to. I'm accustomed to using a mouse with a scroll ball/button, forward/back buttons, and left and right click buttons. I transitioned with ease to this mouse, and LOVE it. I bought it for my work computer, but am considering buying it for my home computer as well. The trackball mouse is very comfortable to use and seems to be helping with my tennis elbow problems. I've been using it for 3 weeks , and overall I'm extremely pleased with the transition. First, I had to set the trackball sensitivity. It was just awful until I found the setting that worked best for me (just a few tries with an easy to use interface). Then, I had to figure out how to use the trackball. This sounds odd, but I wasn't sure if I should use my index finger, middle finger, or both. Ultimately, I use a combination of my index and middle finger on the trackball, and use my ring finger for the right click button. This was an intuitive/thoughtless transition. Thumb buttons and accessibility: Using my thumb for a left click was also a very easy/thoughtless transition. I was less confident about the placement of the forward/back button, as they're above the scroll wheel, but I've found this isn't an issue at all. The hardest adjustment has been the scroll wheel. There's just not as much movement capability with my thumb as there is with my middle finger (which is what I used to control the scroll wheel on a traditional mouse). I can do it, and I've adjusted, but it's slightly more effort than a traditional mouse. As an alternative, I can press the scroll wheel button, which then allows me to control scrolling with the trackball. After 3 weeks of office usage, I'm thrilled. With the exception of very few tasks (relating to precision work, like drawing in paint which I do very little of) I'm 100% converted and competent with the trackball. I expect that as I continue to use the trackball, my comfort in using the trackball for precision work will increase. To conserve the battery, the mouse goes to "sleep" after some period of time, but it wakes up quickly with the click of the mouse. I've yet to charge it, you do need a USB-C cable to charge it. I can't comment on it's suitability for gaming, as I use it at work, not home. Given my challenges with precision use of the trackball (like for drawing in paint), that would definitely be a more difficult transition for me were I to try it with any of my first person shooter games. To be very clear - I can move the trackball around just fine in word and for selecting links, etc. It's literally just things like trying to free draw a straight line in paint or something similar that I'm not as good at, yet. If you're considering a trackball mouse (and you're not left handed), this is a GREAT choice. The functionality is excellent and it's very comfortable to use. I appreciate the color choices available, and the price at $32 was reasonable.
Review: Excellent product, and outstanding customer support!!! - I absolutely LOVE this mouse! I have a tear in the tendon of my right wrist, and using this mouse has made all of the difference in the world, by taking the pressure and strain off of my wrist. After just a few days of using this, the pain has diminished greatly and even the swelling has gone down. It's very ergonomic, and operates very easily and smoothly. Also, their support team is OUTSTANDING! I'm extremely technically challenged, and they were able to walk me through setting it up, and answer ALL of my questions. I normally hate "chat" discussions, but they were amazing, sending me detailed pictures and diagrams of what I needed to do. The mouse itself is very well made and high quality. I am SO pleased with my purchase, and their customer support!

### ⭐⭐⭐⭐⭐ Finally!!!
*by T***A on June 27, 2026*

I had been using the center ball logitech mouse for a loooong time. Was really tired of the cord, and I had been searching for a wireless that felt like the logitech. All others almost hit the mark but there would be something I didn’t like. The angle of the ball, the scroll wheel, latency issues, etc. small things. This one hit the mark!! I love this mouse. It feels so comfortable and mimics the feel of the logitech. It also can connect to 3 different sources. Super handy since I have 3 different computers. So happy with this purchase!!
