Nulea Wireless Trackball Mouse, Rechargeable Ergonomic, Easy Thumb Control, Precise & Smooth Tracking, 3 Device Connection (Bluetooth or USB), Com...

This mouse look really nice compared to other ones out on the market. The white and red combo really makes my desk shine. The functional aspects of the mouse is all there. The tracking works really well, buttons are responsive. Additionally customer service is top notch. Highly recommended. Also this is a good conversation starter, whenever someone sees the mouse they also ask about it, haha.

I have sorta smaller hands so I liked that this wasn't too bulky, which mouse styles like these can be. I love the white color, yes it does stain a bit but I am also a slob and eat at my desk. I wipe it down with a clorox wipe every now and again but it does leave discoloration at the most used parts. I personally am OK with it because it still looks great and I didn't get it just for the color. Track ball is smooth, ive had it 3 months now and it doesn't "stick", the scroll wheel works fast and smooth for when dealing with an excel worksheet that doesn't seem to end, lol. Very pleased with this, especially considering it was cheaper than a bigger name brand for the same color, and that one was bigger in size which I didn't care for.

I needed this to connect to pultiple devices (PS/laptop and tablet) This worked exactly as I had hoped! Connected easily with USB Dongle as well as BT. I bought this at the same time I also tried a similarly priced ProtoArc mouse. While the PA was decent and worked well, it wasn't as smooth, didn't pair/connect via BT to one of my 3 devices, and ergonomics weren't as nice (scroll wheel was at a strange angle & canted off to the side strangely). So in that, the Nulea wins out for sure! Also, this was to replace my existing Logitech M570 wireless trackball mouse. I always loved my M570, I just needed multi-use capability. IMO, this is almost exactly the same. Maybe a bit smoother actually. The Nulea is a tad bigger/taller, but overall the angles/hand positions are close to the same where I can't really notice the difference. Can't comment on the battery life as I have only had it a day, but overall if you like the M570, this will be a great replacement - for a lot lower cost! Compared to my

I like it very easy to use, works well but the connection with Bluetooth is erratic at least on my 2015 MacBook pro but work well with the usb dongle.

UPDATE (1/5/2024): Shortly after leaving my review, Nulea customer service reached out to help with my concerns. While I still would like to see a better coating on the white trackball, I appreciate that Nulea stands behind their products and would have no concerns buying their products in the future. As noted, the black model would not have been fine, and I like the various color options for the trackball itself. Battery life update - I haven't charged since my original review, and it's still going strong even with daily use for work. So far so good. ORIGINAL (unedited): The only thing about this mouse I dislike is how easy it stains. I've owned the white version of the mouse for less than 90 days, and it's already stained from usage. I tried using water, dish soap, and magic eraser, but nothing helped. I have owned other white peripherals for years, and this is the first and only one has stained. When buying a WHITE mouse I expect it to stay white. If you care about having a white trackball, spend extra money to buy the other brand - their coating will hold up and won't stain. I regret this purchase and would return/exchange it if possible. After having 7+ logi trackballs develop the "double click" issue just out of warranty, we decided to give another brand a try. In terms of trackball functionality, it works perfectly. It's the same popular style and shape. The Bluetooth connects well, and I have yet to have any charge/battery issues. I can't speak to the longevity of the internal battery or the clicking/double-clicking yet. I'll update this review if I use it long enough. If you don't care about color, then the dark one is probably a safe buy. For my money, I'd probably just buy logi and just know it's got 24 months before i have to get another one.
