I’m honestly blown away by this thing. I’ve had it about two months now and I haven’t had to charge it once. I’ve put roughly 100 hours of gameplay in since buying it, and still haven’t had to charge it. It automatically shuts off after a few inactive minutes, but wakes back up quickly with a click. It’s not as large as other trackball mice I’ve seen out there (razer basilisk for scale), but the trackball is a good size and easy to maneuver. My PC is finicky with Bluetooth but the 2.4G usb adapter that’s tucked in the bottom of the mouse connects flawlessly. If you haven’t used a trackball mouse before, I highly recommend this one as a good place to start. It’s very ergonomic and easy to get used to, and it’s much more reasonably priced than a lot of the bigger name trackballs.

I have carpal tunnel and this trackball offers improved comfort, precision, and my wrist no longer hurts. The functionality is excellent and easy to use. Excellent value and highly recommended.

It seems to work fine, the mouse is smooth, and it paired easily. It is a little big and you have to get used to the thumb being the right click if you have been using a ball mouse with your index finger using the right click.

This was my very first trackball mouse and it CHANGED MY LIFE! As being in marketing/Arts Management (Art Director) world, I am always editing images and videos and this mouse is so much more precise than a typical mouse for those more detailed/close up edits that you need on pixels! The battery life is crazy good (I’ve only charge it twice in the 8-9 months that I have had it and I use it 8-9 hours almost every day)! If you pop the ball out occasionally and clean the lint and dust out, it works seamlessly but make sure that you set the DPI on the bottom to the best mouse speed that works for you. The only complaint that I have about this mouse is that over time and lots of use, the side roller/scrolling button does not work very well and it is pretty annoying when trying to scroll because when you’re not clicking it inwards to auto-scroll but to regular scroll, it won’t scroll and if you push a little harder to regular scroll, it always clicks it inwards to auto-scroll. Since it is a cheaper trackball mouse, it is not much of an issue to buy another one 3/4 of the way into the year. I am about to order another one but have already ordered 2 total to have one at the office and at home! Worth the price for sure!

It's a comfortable mouse to use and has a rollerball that is very easy to remove and clean - something that should not be underestimated.

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.

Esperaba más de este mouse, se ve de calidad. Es cómodo y práctico. Pero con un solo par de días de uso el click izquierdo, se empieza a quedar trabado, problema por el que quería cambiar mi anterior mouse, que presentó el problema después de años de uso. No recomendado

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 tempsNOTE : Modèle pour DROITIER UNIQUEMENT (dommage de ne pas l'avoir précisé dans le descriptif de l'article)

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.
