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

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.

These mice are fantastic. I've been using trackballs for 10 years. If you're new to trackballs, stop reading and just buy this one. One thing you won't notice as a beginner is what you're missing out on. These Nulea Trackballs are buttery smooth - on par with Kensington which is the best in the biz. The only issue I have with these, and all other trackballs, is that they eventually get stiction. Could be from crud. Could be from the ball getting scratched, or the bearing losing its shape. Heck, it could even be from the temperature changes in my hot office warping the plastic slowly over time. It will happen to every mouse. At this price point just keep buying these anytime that happens. You can buy 4 or 5 of them for the price of an Ltrac or Kensington, and those mice develop issues too. This one feels good in the hand. The rubber feeling does wear off gently but not in an ugly way at all. I wish they made this with a gaming sensor. That's about my only gripe. That and I would prefer the scroll wheel be vertical instead of horizontal. Great mouse. Pick up a couple at this price. Use Marble scroll and Xmouse to map some combo buttons and you will be leagues ahead of everyone.

First trackball mouse I had was the Kensington Expert Mouse, remember?! I LOVED IT over the regular mice of the day! I then upgraded to a Kensington Orbit trackball and I thought I was something with that wheel. Then went with the grey Kensington Orbit Wired Trackball for a while opting for wired for video editing... then a wired Logitech Trackman Marble Trackball... before switching back to a moving mouse, the Victsing Vertical Wireless Mouse. I actually really liked the "vertical ergonomic" nature of the latter. However, with big screens of today, I tired of using the regular mouse in a limited area picking it up to continue large movements... Picked this guy up last week, and I LOVE LOVE it! Got back the hang of the trackball, and no more sore wrist. I can scroll with my index and middle fingers across the entire screen in a sec... but also pinpoint slow and accurate movement just as easy. I can use my ring finger for right clicks. I'm getting my dexterity back with my thumb using it more than I did with my vertical mouse. The buttons are super soft with a nice silent but very slightly audible "click". The wheel is convenient, also used with the thumb. The ball is super smooth, key will be to keep it clean underneath to keep it moving smooth. The ergonomics don't tire the hand a bit, not at all! Benefit of trackball is it stays stationary! Don't need any room to move it at all! Time will tell if the ball movement stays smooth, but I think with simple cleaning, it should. I use this for video and audio editing, as well as for business apps, it's perfect for all of it. Haven't charged it even once after a couple weeks use, so happy about the wireless functionality, should last a long time on a charge! So glad I found this!
