Nulea Wireless Trackball Mouse，Rechargeable Ergonomic Mouse, Easy Thumb Control, 5 Adjustable DPI, 3 Device Connection (Bluetooth or USB) for PC, Laptop, iPad, Mac, Windows, Android

This was my first trackball mouse after careful research. I've been using it for 18 months continuously on a near daily basis and am very pleased. The only issue I've had is the rubber tread on the scroll wheel started to slip after about 6 months use, but was nothing a drop of super glue couldn't solve. The mouse is comfortable under the hand but takes some getting used to if you've never had a track ball before. My preference is to have the track ball under my fingers rather than at my thumb, and I have gotten very good at flicking the mouse cursor across my three 27" screens. I've had to recharge the batteries a total of 4 times in 18 months, which I think is excellent. I would maybe class it a touch on the pricey side (I'd love to have a second for another PC), but can't quite justify the cost for something that will only get used occasionally). As a one off purchase though it's worth it.

Good fit to hand Works well

having used a ball mouse for years this mouse works really well the scroll wheel works as it should the buttons work except one very comfortable to use, shame all the buttons done come up so you can program them I have had ball mice from most manufactures the giant mouse ball was my favourite and for how long they last if you take time to keep them clean its a no brainer

After a few hours of getting used to it, its greate. Make sure to adjust the dpi and cursor speed in the windows settings, so you can get it just right. I'm never moving my hand again, only my fingers. It funny you have to basically re-learn how to press the LMB, because its on the thumb now, but it's not the end of the world. I bought this because I wanted to try it for the first time and I admire the ergonomics of not having to move your whole arm to move the cursor, and I dont regret it. The quality is the average $30+ mouse out there, not cheap plastic. Its bigger than most mice, but its nice to use on the palm.

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.

This is an excellent trackball, I know it will take a little time to get fully used to it, but I found it to be best one I have ever used so far. It fits your hand ever so well. The Bluetooth connect is great. The fact that the buttons are not programmable is actually a good idea, it means the trackball mouse does exactly what it was designed to do brilliantly with no messing about with other software interface etc. Keep up the great work Nulea. I am going to keep an eye on Nulea, as I understand they are a relatively new startup, and if this product is anything to go by, I can only expect great things to come from them.

Love this product. Really easy to operate

Cheap, plasticity and light. Does the job but not premium as described.

Tras más de 6 meses y con más de 8 horas de uso diario, puedo decir que es un gran producto!!! Cuesta acostumbrarse viniendo de un "ratón normal", pero es extremadamente cómodo, la muñeca o dedos no sufren para nada, utiliza menos espacio que un ratón convencional (al no tener que desplazarse en ninguna dirección) y la batería dura mucho (en todo este tiempo solo lo he tenido que cargar 2 veces, y el ratón funciona mientras está cargando). Lo único a tener en cuenta es que los rodamientos deben limpiarse continuamente para asegurar un movimiento "limpio". Es una tarea muy sencilla que se hace en menos de 1 minuto (extraer la bola y limpiar con un paño) Solo puedo decir cosas buenas!!! NOTA: el material no está marcado y mantiene su aparicencia como el primer día.

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.

Just received it and unboxed and tried it out. First impression is that the design is exactly what I am looking for and how it feels while being used. The texture is pleasing (although I have doubts that this matt texture can survive more than a year’s use of daily 5 hour use) and the positions of the trackball and buttons are placed where I want them. Both left and right click buttons click downwards and not inwards which is a positive thing for me. The DPI switch which easily allows me to determine the speed of the arrow travel each time I touch the ball is a godsend compared to other trackballs. This trackball has a rechargeable internal battery - which I hope will last a long time. Always found that rechargeable devices often die due to the battery. It comes with a 2.4Ghz dongle or useable with Bluetooth connection. I have not tried using the rechargeable cable as a direct wired connection to the computer yet but I do not think a wired mode is an option. Will update on this later. Overall on initial impressions and use, this trackball is better than I had hoped and as a trackball user (Microsoft, Logitech, Elecom, etc.) this has so much promise. I will update again in a few months. If my impression is sustained through use in the months ahead, I plan to buy a few for my family and myself at home and office.
