Nulea M507A Wireless Trackball Mouse, Ergonomic Comfort Design with Larger Thumb Trackball & Longer Palm Rest, 5 Adjustable DPI, for Windows, PC and Mac with Bluetooth and USB Capabilities

After using Logitech ball mouse for years I decided to try this model and brand. It simply works great. Smooth scrolling that can be adjusted from the mouse itself. 3 different connection methods. Fits my hand perfectly. Use it frequently and have not needed to recharge the battery. Great purchase!

Great so far, connected via the dongle with no issue.I do wish the shape was a little more ergonomic, like another commenter said, the extended palm rest could be elevated a little more as right now its easy to slide your hand slide off it. Also regarding DPI, a finer adjustment scale would've been welcome as I seem to be right in between two different settings. The DPI button is a little awkward too considering it is noticeably elevated and your finger is positioned nearly on top of it given the shape of the body.I do like the buttons and they have all been responsive so far. The larger ball is incredible and should be standard. The materiel feels nice but the shape of the mouse ends up making a little slick. The ball is extremely smooth and feels great.Is this the peak of ergonomic mouse design? No. Is it one of the best options on the market and worth the $30? Yes.

After my 3rd Logitech Trackball died (they lasted two to three years each), I decided to give this one a try. It has a large footprint, which makes it comfortable because the palm rest is large and ergonomic, and the trackball is also large, making it easier to scroll. As with all trackballs, it seems to take a little time to acclimate to the ball versus scroll ratio, but the adjustment was quick and I appreciate the comfort and design of this Nulea trackball. It offers USB, and two Bluetooth settings, I went with the USB, which was very easy. Hopefully this will last a long time.

After years of ordering Logitech trackballs and maybe getting a years use out of them at $60 a pop I gave this a try, its every bit as good and has more functions at less than half the cost. Highly recommend

I have two of these that I bought nearly a year ago. They are very similar tot he Logitech trackball and function the same. One minor but irritating feature is that you have to tap the buttons to wake it up after a short period of non-use. The biggest problem is that recently it keeps dropping off Bluetooth. I'm using the same computer for both, one at home and one at work. It's not a Bluetooth issue with my computer as my head set and the MX Anywhere mouse stay connected and reconnect readily. On the positive side, it works smoothly and the keys are responsive. the battery lasts a long time and it can be operated while plugged in. If you are wanting to try a trackball this is a cheaper alternative to Logitech and they worked fine for a while

I am very disappointed, I have been waiting for this trac ball for my work. It shows up with no dongal for the USB receiver. No charging cable and I don't know if the ball was supposed to fall out so easy. Very disappointed.

Each time I used my regular mouse It was making noise as I moved it around my desk. Bought this due to the Bluetooth capabilities and the thumb trackball. I will never go back to the old style mouse, this mouse has changed the way I work. I own an online marketing agency and am online 8 to 12 hours a day working. This mouse took a week to get comfortable with, but now I will never be without it. Effortless and quiet movement around my screens, I love it. Customer service is the best in the business, Nulea is the only product I will buy again. Highly recommended

After using mice for years I became interested in using a trackball on commercial flights where the fold-down tray tables leave no room to use a mouse and track-pads compete with my hands for control of the cursor. My first trackball acquisition was a Logitech that I liked very much, but it failed after only 4 months of use (Is that why they have a 90-day warranty?).Not wanting to spend the asking price for another Logitech, I decided to try the Nulea M507A. This trackball has a number of great features and one drawback, described below:PROs-* USB rechargeable - no more disposable batteries.* Forward/Back buttons for browing.* Both Bluetooth and USB receiver connectivity.* Button-selectable precision - no more going back to settings to make adjustments.CONs-* The second item under "About this item" says "Longer Palm Support" and they aren't kidding. I have medium-large hands and this trackball has taken some getting used to. I do like the large (36mm) ball, but the larger frame has been a bit of a distraction. If you have smaller hands you might want to consider the Nulea M501 that has similar features but in a smaller form factor for just a couple of dollars more.

Absolutely the best Trackball I have ever used! The surface has a non-slip rubber coating which is brilliant. The increased size body and ball make it super comfortable to use. Nothing negative to say about this product, will be recommending to all my friends, & customers.

I was not sure what to expect; I have tried the Logitech competitor a few times and the Amazon competitor last time and this one stacks up very well. It is larger and has the larger footprint, but it still fits on my laptop (17" LG and not used for gaming at all) beside the trackpad. It has better 'feet' than the Amazon, and does not require an anti slip pad under it. Since it has a rechargeable battery, it should also last longer than the Amazon as well. The price is great, the ball is identical to the competitors. It is not perfect though: it sometimes starts (or restarts) at a different scrolling speed which I find too slow for my non gaming activities; this seems to happen if I switch the mouse on at about the same as the laptop is booting... Cycling power off and back on corrects it. I like the USB-C connector on it, but I have no idea how a charge would last as I have only had it for less than a month. So far I would recommend it.

Idéal pour mon souci de canal carpien. Nuléa au top.J'ai acheté plusieurs modèles Nuléa (M501, M505, M507) et tous sont très bien. Je m'en sers alternativement pour modifier mes positions de travail et éviter mes mouvements trop répétitifs qui aggravent mon syndrome de canal carpien droit.Je les ai eu tous entre 30 et 35€. Hélas certains ne sont plus trouvables et les autres ont pris 10€ !!Difficile de les trouver ailleurs...Bon produits, qui tiennent la charge longtemps, marchent sur les smartphones grâce à la connexion bluetooth (pas mal de les appairer avant que vous ne cassiez l'écran de votre smartphone... 😏).Utilisable sur PC sans dongle en bluetooth aussi bien entendu.Parfait en 1 mot, si le prix n'augmentait pas !

elle est massive , , il faut que ma mains s habitue a la tenir et manipuler la boule avec le pouce . il lui faut de l espace et un tapis de sourie conséquent a sa taille .pour le reste c est que du confort , surtout qu'elle peut commander jusqu' à 3 appareils , avec une simple pression pour passer de l un a l autre . + une clef Bluetooth pour les vieux pc qui n en ont pas .un bon produit a prix correct , j en suis satisfait .

The media could not be loaded. Ratón de bola para manejar el pc con el pulgar que se ha convertido en un accesorio indispensable para mi trabajo diario, pero no tanto para mis horas de juego. La verdad es que no había probado este tipo de ratones hasta ahora y el diseño me parece muy ergonómico sin estropear la funcionalidad que se le espera a un ratón. Lo único no he conseguido tener la misma habilidad en los juegos que con el ratón clásico de toda la vida. También es cierto que llevo muchos años usando el clásico y menos de un mes con este tipo de diseño.Si tuviera que destacar algo frente al resto de características claramente seria su ergonomía. La forma del ratón se adapta perfectamente a mi mano (que es bastante grande, como el ratón), lo que lo hace extremadamente cómodo durante largas sesiones de trabajo. No te das cuenta de esto hasta que lo llevas durante varias horas y al no tener que mover para nada el brazo notas que te cansas menos.Además, el ratón ofrece cinco configuraciones de DPI ajustables, con lo que se puede personalizar la sensibilidad del ratón para adaptarlo a diferentes tareas, desde la precisión necesaria para el trabajo de diseño hasta la velocidad para los juegos de acción (aunque como ya he dicho no consigo una precisión tan buena como con el tradicional de toda la vida).La conectividad es otro punto fuerte con opciones dos opciones inalámbricas, algo no muy habitual en ratones. El hecho de que pueda conectarlo mediante Bluetooth o USB (incluido) me permite usarlo en pc que no tengan bluetooth de serie, algo habitual en los pc s antiguos que abundan en mi trabajo. La instalación y el emparejamiento son sencillos, y la conexión Bluetooth es estable y no me ha dado ningún problema.En cuanto al diseño el color negro y la bola roja le dan un aspecto moderno de lo que suele encontrarse en periféricos gaming. Pero lo que realmente enamora son las luces LED RGB que rodean la bola. Estas luces crean un efecto visual que le dan un toque de alta gama a mi escritorio. El aspecto es gaming pero sin llegar a quedar mal o ser excesivo.Por la parte de los materiales el fabricante ha cuidado cada aspecto de este ratón, desde los botones hasta la carcasa. Además, se siente sólido y resistente en las manos a diferenciar de otros ratones que denotan fragilidad.Para mí se ha vuelto un indispensable que, sin duda, merece cinco estrellas. Siempre viene conmigo desde que lo tengo en la mochila del trabajo.
