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

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.

I already found a replacement to my Logitech mk570 and was looking for another because my partner likes to take mine. I was going to just order another however I found this one. I still bought the other too. I ended up keeping both mice. So this one took some time to adjust to. The shape alone makes this stand out from standard trackballs. The button layout is different and the mouse is larger than my small hand is used to. Once I did I found the mechanics were much faster than the other standard trackball mouse layout. It's a lot faster to scroll with my fingers and gives my thumb a rest. Left clicking with my thumb is easy and has a soft but solid click. Using my thumb on the scroll wheel was different but also felt natural over time. I do not use the forward or back buttons much but they feel are a little too high for my thumb to comfortably press. Trackball feels the same as the others... it's just in a different place. The space beneath it makes it easy to pop out for cleaning. All the buttons feel nice and work well. I love the connectivity of this. I have it paired to my pc via USB, my phone via Bluetooth 2.4 and my laptop via the Bluetooth 5. Switching between the devices is super easy. The battery lasts awhile too. I go for over a week or more and only plug it in when the light blinks trying to use it and nothing moves on my screen. It only takes an hour until it's ready to use wirelessly again. I still use it when it's plugged in charging. The mouse is smooth but is a grippy matte. That took adjusting to as well because my other mice are smooth hard plastic. Lastly, the price is amazing for the durability and quality of this mouse.

I am searching for a cordless mouse to replace my worn out Logitech Trackman that is just way too expensive to replace for $179. This mouse is very nice but a bit large (hard to believe there is an even larger model size available). The surface has more of a grip to it - not super smooth. The tracker ball is a bit large also (golf ball size, maybe a little larger). The thumb clicker could probably be a little less indented since it is an unnatural placement for the hand. I usually use a wrist support and have tried this mouse with and without that but already feel some fatigue at the top of my wrist and arm so might need to keep searching. Aside from the size being a bit too large and bulky, it is great - very responsive, works right away, and stylish.

I absolutely love this mouse. I am physically disabled and use it to control my iPad (and sometimes my iPhone from bed. The trackball is large and allows me to move around my screen like I would on a computer and multitask and work. There are multiple programmable buttons I use to control the volume on my devices, switch apps/tabs, and to right/left click. It is equally useful when I use a laptop while in my wheelchair. I have dropped this mouse many many times because I have hand tremors and muscle spasms and it (and the track ball) have never broken. It seems extremely high quality. It stays charged a long time.

Article bien conçu, esthétique et complet avec le trackball (mouvement du curseur), des 4 boutons latéraux et de la molette permettant de scroller. Avec cette configuration, on doit revoir ses habitudes étant donné que l'équipement ne bouge plus contrairement à une souris standard, mais uniquement la boule avec les doigts > Même si l'équipement est imposant, ça reste un choix judicieux quand on a un petit poste de travail ou que la surface est vitrée - soucis avec le laser des souris optiques (d'autant qu'il peut aussi servir de repose-main) Ce modèle est sans fil grâce à son dongle (là aussi on évite un câble qui traine sur le bureau) La batterie [non remplaçable] se recharge via un port USB-C (câble fourni) et j'espère qu'elle durera dans le temps NOTE : Modèle pour DROITIER UNIQUEMENT (dommage de ne pas l'avoir précisé dans le descriptif de l'article)

Now I've gotten used to it, I like it. First "ball mouse" I've ever used in 30+ years so my muscle memory took some time to adjust. It comes with a wireless USB dongle (plugged into the base). Or you can use Bluetooth mode - there's a button on the bottom for switching modes. I've used both wireless USB and Bluetooth and they both work fine. I like the fact no mouse mat is needed. It works on my coffee table or on the sofa next to me. I wanted a top-ball mouse as my thumb is not as dextrous as my fingers. My right hand sits very comfortably on the mouse. The mouse has back+forward buttons which are handy in web browsers for going back a page and then forwards to the previous page. No need to move the mouse to the top left of the screen for the "<-" and "->" browser buttons. I charged it up on arrival. USB cable included for this. It's been running a week on a single charge, and I've been using it a lot. My previous mouse (single AA battery) would have died by now. The ball is removable for cleaning and has a decent weight to it. It'll hurt your foot if you drop the ball on it (I did this...). If you don't have space for an A4 mouse mat, or simply want to use a mouse on a sofa cushion without it sliding all over the place, then this is ideal.

La trackball arriva dentro una scatola di cartone, al suo interno troviamo anche: un cavetto usb ed il manuale multilingue compreso l’italiano. Il cavetto usb serve per caricare a batteria interna della trackball, ha un connettore tipo A da collegare ad un alimentatore, ed uno tipo C da collegare alla trackball. Sotto la base della trackball si trova la chiavetta usb per il collegamento wireless. Sempre sotto troviamo un pulsante per selezionare i dpi, un pulsante per selezionare il tipo di connessione fra i tre disponibili (2 canali bluetooth ed 1 canale wireless), 3 led che indicano il canale selezionato ed un selettore per accenderla o spegnerla, la porta usb tipo C si trova davanti in basso, il cavo non intralcia nell’utilizzo. Nella parte superiore troviamo la palla al centro, la rotella il pulsante sinistro ed i pulsanti avanti/indietro sul lato sinistro ed il pulsante destro nel lato destro. Data la disposizione il pollice deve comandare il tasto sinistro, i tasti avanti/indietro e la rotellina, tutti questi comandi per il solo pollice non li trovo naturali e mi blocco molto spesso, sicuramente bisogna abituarsi ma preferisco la palla a sinistra ed il resto dei comandi dorsali. Ovviamente non potevo sapere che questa configurazione mi avrebbe messo in difficoltà e certamente non ne faccio una colpa alla trackball. Il pulsante sinistro e destro sono di dimensioni generose, i tasti indietro/avanti sono di dimensioni generose, il terzo pulsante è la pressione della rotellina. Il pulsante dei pdi in questo caso è sotto e poco adatto per cambi al volo, di solito viene messo vicino alla rotella per agevolare il cambio. La forma della trackball obbliga l’uso della mano destra, non è adatta per l’uso con la mano sinistra. Per la lettura della palla credo venga utilizzato un diodo all’infrarosso perché non si vede nulla di acceso ad occhio nudo. La palla si sfila per pulire il sensore quando inizierà a non funzionare bene, sotto è presente un foro per premere la palla fuori dalla sede, a quel punto il sensore è a vista. Consiglio di trattare bene la palla perché il sistema di lettura traccia la sua superfice, eviterei anelli o altri oggetti nell’utilizzo della trackball. Come scritto, è possibile associare la trackball a tre differenti dispositivi, due dispositivi tramite il bluetooth ed uno tramite la chiavetta wireless fornita, non è possibile comandare tre dispositivi contemporaneamente, solo uno alla volta, si seleziona il dispositivo con il pulsante sotto la base. Nel complesso la trackball funziona benissimo, assegno 5 stelle.

The Nulea Wireless Ergonomic Trackball Mouse is an excellent choice for those seeking comfort and versatility. Its ergonomic design and 44mm index finger trackball provide a smooth and strain-free experience. The mouse is offers Bluetooth connectivity, making it compatible with various devices including PC, laptop. With 5 adjustable DPI settings, it caters to different sensitivity preferences. Overall, it’s a reliable and user-friendly option for enhancing productivity.

Pour ceux qui aiment travailler avec un trackball, il est parfait (PRESQUE). Le seul inconvénient que je trouve est : Pourquoi mettre le bouton ON/Off sous le trackball ??? Cela oblige à retourner à chaque fois le trackball pour notamment l'arrêter avec un curseur qui se déplace à l'écran parce qu'on retient la boule et le risque d'appuyer sur le bouton de gauche ou droite en même temps. Merci les constructeurs de réfléchir à cela ! Sinon il est vraiment top.
