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

I’ve been using Logitech up until now, but this is the best ergonomic mouse ever. Perfect fit. No batteries. Stays charged for a long period of time. Highly recommend it.

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.

This is a good looking trackball, and the trackball itself works well. The scroll wheel is slow, and does not have an adjustable resolution. The back and forward buttons are not compatible with Mac. It is comfortable to use. Update: Customer service took my complaint seriously and thus I have upgraded my rating. Second update: I was again contacted by customer service as they followed up with me on my problem, at this point I have to give their customer service 5 stars, It is great to deal with a company that backs their products. This alone makes me feel like a valued client.

Perhaps I should start with two statements that would summarize this product: 1) No products from the brand of this one, Nulea, has disappointed me, and 2) This is a great controller, but only if you are (or if you get) used to using trackballs.If you are not used to it, it takes some time to get comfortable with using a trackball. Using a regular mouse involves moving the mouse with your WRIST while pressing (or not) the buttons. With trackball mouses, you move the pointer by rolling the trackball with your FINGER(s). It is easy to use, but I am sure it will take some time to get used to doing it fast and naturally. But their plus is that you do not need a mouse pad or any flat surface with traction (for mechanical mouse) or with texture (for optical mouse). In addition, since you do not move the trackball mouse, you do not need to allocate space (such as the space for a mouse pad) to move it on your desktop (or couch).The next thing I would like to talk about is the connection. Most of the wireless mouses use a USB dongle to connect. I like Bluetooth connection better as it does not require a USB dongle and does not occupy one of the USB ports with the dongle. In addition, the dongles are usually of type USB-A and now we are having more and more devices with C-type USB port(s) only. This mouse sports a USB dongle as well as two Bluetooth connections, so you have your options.Its ball is located towards the center, so you will move it with your index finger (maybe with the help of your middle finger as well). There are other trackball mouses in the market that require to be moved by your thumb; those might be easier to switch from a regular mouse.Its size is fairly large, good for resting your hand on it, but a bit awkward for those who are used to holding the whole mouse in their to move their non-trackball mouses. The weight seems fine, not too heavy, not too light, heavy enough to rest robustly on the surface you put it on. When I pick it up though, I usually press one of the buttons inadvertently.Its DPI options are very good, from unbearably slow to very hard to do small moves. The DPI switch is at the bottom, so you have to turn the mouse upside down, press the switch, turn it back right side up, see if it is the right DPI for you, and if not, repeat (possibly several times). While this prevents from accidentally pressing the DPI button (if it were placed on top as with most mouses), it is also very cumbersome whenever you change the DPI.The user manual comes in English, French, German, Italian, and Spanish. Unfortunately there is no information on how to program extra keys. Aside from the two click buttons, there is a scrolling wheel with its own push button + two more (forward/backward) buttons.Overall, it is a great trackball. The price of $32 CAD at the time of writing seems fair. I would strongly recommend it if you use or are willing to switch to a trackball.
