Nulea Wireless Ergonomic Trackball Mouse, Rechargeable, Bluetooth Rollerball Mouse, 44mm Index Finger Trackball, 5 Adjustable DPI, Compatible with PC, Laptop, Mac

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.

This trackball mouse has been a great addition to my setup. It works flawlessly across my Apple devices, Xbox, and PC. The ergonomic design is incredibly comfortable, especially for long hours of use, and since it’s a trackball, there’s no need to move the mouse around—just smooth, precise control with the ball.What I really appreciate is the flexibility in connectivity:- Bluetooth pairs instantly with my MacBook.- Wireless USB dongle works perfectly with my PC and Xbox.- The USB-C connection not only charges the mouse but also allows for a wired option when needed.The mouse feels lightweight and sturdy, and the trackball itself is responsive and smooth. I’ve experienced no lag, whether I’m scrolling through documents or navigating games on Xbox.Another great feature is the ability to adjust the mouse sensitivity. You can tweak the settings through the operating system, but there’s also a push button at the bottom of the mouse for quick sensitivity adjustments, which is really handy for on-the-fly changes.Battery life has been excellent. It charges quickly via USB-C, and I can go days without needing to recharge. The convenience of not having to move the mouse around has really reduced strain on my wrist.Overall, this is a great trackball mouse. It’s ergonomic, versatile, and packed with useful features, making it perfect for multi-platform use. Highly recommended.

I have been a fan of the Elecom Huge trackball for years, I found it to be best replacement for the MS Trackball Explorer from years past, though it was a completely different design. When I saw this trackball, it reminded me so much of the original Trackball Explorer that I had to give it a try. This review will mostly be comparing it to the Elecom Huge.Buttons: While I love the Elecom Huge, it's not really designed for smaller hands like mine. The left button on the Huge is a bit too far away for my thumb to reach comfortably, so I have had to swap the Forward and Left buttons in the software, not a big deal as it's easy to do, but it's an out-of-the-box ergonomic drawback. The left button on the Nulea is more "flared" out, so it's much easier to reach with my thumb (by pressing "downward" instead of "inward") and therefore requires no re-mapping of buttons.Which brings up another important difference: you cannot re-program any of the buttons on the Nulea, fortunately, the buttons are laid out in a familiar pattern that is easy to learn, but could be a showstopper if you don't like the current button assignments and don't want to mess with third-party utilities.The Elecom also comes with 3 extra programmable buttons and can do horizontal scrolling, which the Nulea is incapable of doing.** UPDATE: I thought I would miss having the extra re-programmable buttons, but it hasn't affected me that much at all **Ergonomics: The Elecom has a flatter design with a nice soft rest for your palm and the huge ball makes moving across a 4K monitor screen a breeze as it doesn't require much rolling effort to go from one side of the screen to the other. The Nulea has a more raised design, and while it lacks the soft palm rest of the Elecom, it's still quite comfortable. The Nulea has a smaller ball, so there is more noticeable rolling to get around the screen, what i could do in one smooth motion with the Elecom, requires a little extra afterward to get there on the Nulea even at the highest DPI setting, so i had to adjust the pointer speed in Widows to compensate.** UPDATE: After two months of daily use, it is still very comfortable to use, no stress or strain at all **Battery life: The Elecom Huge can go for months at a time between battery changes, but does require physical batteries. I haven't owned the Nulea long enough to know how long it lasts on a charge, but it uses a rechargeable battery (and USB-C), and you can continue to use it while it's recharging, so that's a plus.** UPDATE: After 2 months of daily use, I have not needed to recharge it. However, it does "sleep" after some period of inactivity, requiring you to click a button to wake it back up. ***Overall: So far I would say if you want a programmable, feature rich trackball, go for the Elecom Huge. If you want a nice comfortable trackball reminiscent of the old MS Trackball Explorer with no bells and whistles, then go for the Nulea.**UPDATE**After 15 months of continuous daily use, one of the bearings failed, causing the ball to no longer roll smoothly. However, I liked it so much, that I have purchased a replacement.
