Nulea Wireless Trackball Mouse Ergonomic RGB 44mm Index Finger Control | Rechargeable mouse with 5 DPI levels,Bluetooth USB connection,3 device switching,compatible with PC iPad Mac Windows

These are beautiful. They are reminiscent of Logitech's well known "Trackman Marble FX" which was discontinued many years-ago. Those were the best shape a trackball was ever made in, but they just stopped making them. They were so good I never forgot, and when I was recently looking at trackballs, I was happy to find this, and a few others, using a very similar shape to the Marble FX. So I ordered one. It was a wired version, and aggressively low-priced. While Logitech knows it's finger-controlled trackballs are popular, after having some sort of patent dispute and needing to discontinue the lovely "Marble FX," they continue to this day to make the smaller, less lovely "Trackman Marble." This is NOT the same as the "Marble FX," which is no longer made. But it's worth noting, I went through at least four "Trackman Marbles" over the years, wearing them out using them every day, and they always cost about thirty dollars - Logitech has now raised the price of that mediocre offering ... the Trackman Marble, to one hundred and eighty dollars USD. Wow!! ... while some innovative companies are actually daring to imitate the beautiful but patent-issue-plagued original "Marble FX" for the first time! I counted three different products, branded differently with some small differences, but they are all basically the same, all clones of a Marble FX. How refreshing! I bought a second one! Before the first one even arrived! The second one I bought is this one, with wireless features. I have it plugged into USB on a Mac Studio desktop* so it will stay charged up, and when my trackpad nags me about charging it, I can just swap that USB cable out of the front of the trackball. Working great so far. It does seem to have a "give me a second" wake-up feature, probably owing to the fact it's wireless so it goes to sleep after awhile. So I just shake it around and it wakes up. This trackball has five resolutions accessible by pressing a button on the bottom of it, and I found a middle value to work well for me. It paired easily with bluetooth. In the hand, it feels comfortable and reminds me of the "correct" trackball design I missed so much from years past! The ball (I got a red one) is big enough and there are buttons galore. I have only used right-click, left-click and there's a nice wheel to scroll. There's a half dozen more button-programmable things I haven't fiddled with. But when I rest my hand on it, my thumb appropriately falls onto the left-click button (which is important!), which has the largest button-surface of all the buttons on that side. It's easy, comfortable and starting to feel like home. *I'm using this with a Mac Studio. It's plug and play, and is working wirelessly with the dongle never removed from its underside (it's using Bluetooth, while that dongle is for 2.4 GHz direct wireless to USB). I have a trackpad AND trackball (a great way to roll) and having just left-click and right-click buttons working out of the box, and the scroll wheel too, is all I'm going to need. I can't comment on usability of the other buttons with a Mac. Maybe I'll try that later. I'll keep both of them. These are WELL WORTH the price (currently under $50 USD). Note from my experience using both this and one of the others that look just like it, they appear to be nearly identical, and there was at least one more I didn't buy which looked also nearly identical. So if you're going for the shape and feel, you'll probably be quite happy with any of them. This one is darker black than the other and has a more velvety surface texture. I'd recommend buying one of these even if you weren't intending to replace your mouse or trackball right now; you'll be glad you did. I had a long history of mouse-caused-wrist-pain which was relieved when I switched to using a finger-manipulated-trackball. I can't recommend this product highly enough! :)

This is a nice trackball. I actually already have a ProtoArc EM01 which replaced my dead Logitch Ergo, which in turn replaced my legendary Trackman Marble. So I was looking for a return of the finger trackball for gaming and possibly an improvement in dexterity and comfort. As is, this overall unit is quite large. Not the biggest thing I've ever seen but noticably bigger than my ProtoArc. The ball itself is huge and very easy to operate. The buttons, like all of them, are also large. In the case of the left click button, possibly too large, as it is very easy to click it when really trying to shift hand positions or to move the base anywhere - like to a different angle. It could be that I've gotten so used to a thumb trackball and the tilt angle I have with it that I need to re-learn this type though, so I don't hold that against it. The scroll wheel is in, what I consider, to be a very convenient place. It's also large though so I have to tuck my thumb more than I would prefer. But when used, it is very positive feeling and precise, so again I don't hold the dimensions against it. The base has a very nice finish and looks high quality, as does the entire unit. I just got it yesterday so I haven't actually needed to clean it, but it seems like that will be extremely simple. Setup on Windows 11 was easy once I got the hang of how the mode switch button at the bottom and the bluetooth search actually worked. You have to switch to the bluetooth channel by pressing but then press and hold until the light blinks. But you have to remember to start the press and hold on the setting before the one you're trying to get to so that the final position when you let go will be the one you're trying to reach. Otherwise, you go one past where you intend. This is a moot point with USB, which is the first position. I've been having problems with bluetooth being very jumpy and intermittent, and that continued with this unit. But that is definitely down to my bluetooth performance specifically because like with the ProtoArc, once I went to the USB dongle performance was glass smooth and quick. DPI switches are also easy and the difference is very noticeable. The button for this is also at the bottom to the left of the mode switch button. Much too easrly to discuss durability but given the construction and finish of the unit I would expect it to last at least as long as a competing Logitech. No rainbow brite LEDs on it either, but who really needs all that when everything else in your system probably already operates as a midnight sun? The charging LED behind the scroll wheel is enough. All told, I gave this five stars. It's exactly what I expected it and hoped for it to be. A great return to the marble way of life.

I've been a trackball user for about 12 years at this point, but the only trackballs I've used have been thumb trackballs. I have had Logitech M570s, M575s, and a couple of MX Ergos. I decided to give a finger trackball a try and the Nulea M505 was reasonably priced for something I may or may not have liked. After I received the Nulea M505B, I had a few day adjustment period to not left click randomly, but by the end of the first day, I can say I immediately loved the design. It's incredibly comfortable, fits your hand well, and the large trackball is something I can say I enjoy a lot more than the typical thumb sized ones. It simply feels more intuitive and more natural to use a trackball this way. I ended up buying an additional one to have on hand for when this one dies and just in case I couldn't find a replacement of the same design. Functionally, you would think that the function of having your right click be on your ring finger be weird, but you adjust pretty fast. All the clicks are easy to register and I haven't had any issues there. Scrolling works well, and the middle click is just the right stiffness so it's easy to press but not accidentally when scrolling fast. The only negative thing I can say about this mouse is the device switching is on the bottom, and I switch between 3 different devices regularly while working from home so it gets somewhat annoying having to lift to switch connections. However, switching to a different device, whether it's the wireless, or one of the Bluetooth connections, it's fast. I have had zero issues when reconnecting to the previous devices and it's always been connected before I even set the mouse back down.

It's really hard to find a good trackball mouse these days but I picked this one based on it's features and price point. It can support up to three devices but the active device selector buttons are on the bottom of the mouse instead of the topside which is really annoying if you need to easily switch between paired devices on the fly. I like it that the mouse is rechargeable, but I have to recharge it more often than my other rechargeable mice so perhaps the light ring surrounding the trackball drains the battery faster than mice without lights. The trackball falls out easily but it pops right back in. Performance wise the mouse is responsive but the button clicks are easily heard in a quiet space which may be disturbing for some people. Overall I've been happy with this mouse even with it's minor design annoyances.

Very comfortable and easy to use. Highly recommended! Has been very helpful in reducing my carpal tunnel issues.

I absolutely loved this trackball mouse, which functioned excellently right up until it didn't. The size and texture was perfect, not cheap plastic feeling. The lights were fun, and the rechargeable battery perfect. The feel and response was spot on. The only ongoing issue was dust would clog on the little plastic nibs that support the ball. And those little plastic nibs are the failure of the trackball mouse after only a year and a half. The trackball doesn't ride on rollers, bearings, or wheels. It rides on three little plastic nibs. After 1.5 years, those nibs are totally gone and moving the trackball is pretty much impossible. I've had to replace the device after only 1.5 years of use. Disappointing since I think it's reasonable to expect many years out of a mouse. It breaks my heart to give only three stars because the device was so outstanding. If they had used bearings instead of plastic nibs, I'd still be using it and this would be a 5-star review.

I've been using an elcom thumb trackball mouse for a couple of years. I was "underwhelmed" when I got that one, as it has a very cheap, jankety feel to it. This one, the Nulea, is what I was hoping for when I ordered the elecom. The Nulea has a very solid feel, the trackball is insanely smooth and satisfying to use. The buttons have a very solid click (my elcom will audibly click sometimes, without registering on the computer. Very annoying.) It has a nice matte finish to it. I imagine that'll probably wear through fairly quickly, but it sure looks and feels nice while it's new. Even though it took me a couple of times to get used to, I prefer the index finger location for the trackball, as it feels easier for me for fine motor skills. It pairs nicely with my PC and my iPad via Bluetooth. I haven't tried the dongle, I'd rather not have that hanging up on my computer bag when I put my computer away. So far, it seems that I won't have to. Yay! The only thing that I am not impressed with is the scroll wheel with the iPad. It seems to vary in speed as you scroll through content (perhaps in relation to what you scroll through? I haven't figured that out yet). I'll be spinning it as fast as I can and the page I'm on will be barely crawling by, then it will suddenly lurch forward at a speed you would expect, then return to it's turtle pace, seemingly randomly. I've only used it for a short time on my PC, but the scroll wheel seems to behave perfectly on it. It came charged, I have not had to charge it yet. Nice not to have to put batteries in it. Packaging was really nice, I typically don't care about that much, but unboxing this thing made me think that it was going to be high quality. I have not been disappointed. I love the size of the trackball, but I kinda wish the whole mouse were smaller. It is reasonably comfortable, but I'd like to take it with me sometimes, and it is huge. There is palm support engineered into the back of this thing. It seems to me that they could have eliminated that by chopping 2" or so off of the back and allowed your palm to rest on the desk, then made the whole mouse 1/2-3/4" shorter, vertically. But, maybe they tried that and this felt significantly better? If your not packing it in your computer bag, it's fine as it is. Bottom line, even with my minor gripes, this is my favorite mouse to date. This thing is solid and is very satisfying to use!

Love these trackballs , I have two of them, they look and work very well.

Estava com receio de comprar, com medo de não me conseguir adaptar. Mas quando recebi e o testei achei super intuitivo, fácil adaptação. Diminuiu as dores do pulso e dedos e neste momento não consigo pensar noutro tipo de rato....

Super comodissimo

Very happy, as has improved my hand pain immensely. I soon got used to the layout.

Liegt gut in der Hand und sehr genau.

The wrist does require a little adjusting and getting used to but it’s a game changer and makes online work a real pleasure. Love the style, smoothness and features - especially the centre roller!
