I believe I bought this mouse around the same time I bought my laptop because I started summer classes the last week of June, I believe, or the first week of July. So I've had the mouse some time, as it's now 8/30/2024. I'm currently having connectivity issues with the mouse. I've never used the USB plug before until a few minutes ago because, for some reason, the mouse keeps disconnecting from my laptop. I'm not sure if it's my laptop specifically disconnecting the mouse, or if it's losing signal. I started doing this about two days ago, and it is seemingly progressing. I did not want to use the USB adaptor because, in the past, I would leave them in my laptops, and I did not want to risk harming the ports since the laptop is usually in my car and could at any moment land or hit against something. I am also using a gaming PC that was created for 2022/2023 but was purchased brand new, so I don't think it's my laptop. If so, it must have something to do with multiple Bluetooth devices being connected at the same time... Such as..my phone. Neither my phone nor my car's audio was interrupted whenever the mouse would disconnect. I will have to use the USB adaptor for now because I'm scared of investing in a more expensive mouse if it has these same issues. My story: I basically live in my car. I’m also a college student so I don’t have much space for my mouse to move around on. I was either running it over my laptop, which made these awful screeching noises like nails on a chalk board, or I’d be fighting with my armrest and trying to adjust my seat constantly. I just could never get into a comfortable position. At first my objective was to buy an ergonomic mouse, out of fear of my hand hurting with the constant micro wrist movements, then I saw these types of mouses. I’m not gonna lie, I was not happy that none of these mouses came in a soft pastel pink color. I really wanted that touch of pink, but I decided to give it a shot. nd the mouse. Okay.. so then.. which one? Well, I was actually going to buy a more expensive one. I knew I wanted to get the device next day, so it limited my selection a bit. At first I thought I needed a trackpad at the center of the mouse, for the best comfort. These were at the 40$ and above price range, and I was considered it. But.. i noticed that a lot of the mouses with the trackpad at the center are too large for smaller hands. I’m so grateful I listened to the reviewer in that devices review section. She complained that it was too big for her, and my hands were measuring 5.6 inches. 3-4inches under the recommended size. I whined a little bit, because it had cool lights that glowed and stuff, but I knew that I could return this mouse if it didn’t work out. Besides, it’s half the cost. The Experience: Well, I’m here to say, I’m very glad I chose this device. My thumb after a day of use while scrolling through documents and course readings hasn’t ached. I also discovered that I can also use my index finger to move the mouse as well, and scroll using my ring finger , and left click with my middle finger comfortably. —-The default would to use your thumb to scroll, index and middle finger to left click, middle finger to scroll, and of course the ring and pinky finger to right click. I’m surprised by how light the mouse is, the only weight in it is the trackball itself. Otherwise, it’s just as light as any other regular mouse. It wa easy for ME to get use to. I’m not a master at it, but I broke into it much faster than I’ve seen others commenting have. Some saying 3-7 days. I believe the quality is nice and fair for its price point. I mean, you have to also realize that it’s more than plastic and a ball. It has Bluetooth connections, a usb port, AND ITS RECHARGEABLE! It’s everything I wanted in one! It’s my first time having a rechargeable mouse, and the first to having one that doesn’t require a usb plug in. Pairing was easy! All I had to do was click the 2 or 3rd connectivity option, and hold it for a few seconds until it started to blink happily. My laptop recognized it immediately, but you may have to go directly to your Bluetooth devices setting. There’s a tiny button below the scroll button, and it allows you to change your cursor speed. The first one was way too slow for me, the second was decent, but I prefer the fast past cursor. The only thing I’m sad about.. I guess along the way of looking at different options, I thought this mouse had the 20 degree angle function, and I really would like to experience that to see if I like it. When using this mouse, my hand kinda slides to the right, and I think that 20 degree angle would help keep my hand in position. I don't want to return it, but I really want to see if I like having this option.

Very nice elegant looking mouse. The wheel is just a little sticky, but with adjusting the speed it’s OK.

Overall good product. I think the size was great and it wasn't that comfortable to work. The reason is you need to constantly use your thumb to move the cursor and after some time my thumb started to giving me problems. It is easy to use but controlling the cursor with the ball is a something you need to get used to. I don't recommend this for video editing or things like that.

fue una excelente opción de compra, muy recomendado toca acostumbrarse al sistema de la trackball pero después uno solo quiere usar solo este tipo de mouse, llevo casi un año con el y sin ningún problema de uso diario, solo tienes que quitar la bola y limpiar los pines que se ensucian cuando empiezas a notar falta de precisión

Great mouse

Worked perfectly for the first 4-6 months but started developing issues. Left click became less responsive and started having battery issues. By the 1 year mark, I have to charge it 1-2 times a day. What is the point of wireless if it's plugged in half the time I'm using it?

I've had several different trackballs over the last 30 years. This trackball performs as good or better than many of the more expensive ones. For the money you can't go wrong. Battery charge lasts for more than a week and it charges in less than a couple of hours. It also works with a USB-C cable if the battery dies while working. Just connect the cable and immediately it works and charges at the same time. I originally picked this trackball because it pared with both my desktop and laptop and with a cable for other systems without destroying the configuration for my two systems.

I recently started a new office job and now spend 8 hours straight on the computer with only a 1-hour break in between. Using a traditional mouse during this marathon of working hours made my wrist and finger joints feel fatigued, hurt, and tired. By the end of the workday, my hand would be in pain. I tried a vertical ergonomic mouse, but it didn't work; my wrist still hurt. So, I had to find another solution. I was deciding between a trackball mouse and a track pad, and I am so glad I chose this trackball mouse. My hand feels significantly better—less fatigue and no more pain after a long, continuous, monotonous workday. The trackball is precise, the build quality is good for the price, and the mouse feels very light and premium to the touch. It's also very affordable compared to other trackball mice. I strongly recommend this mouse for anyone working in an office or struggling with wrist pain while using a traditional mouse. The trackball does take some time to get used to, but with practice, it will become second nature for the user in no time. It took me two days to learn how to properly navigate the mouse cursor using the trackball, but now I feel proficient with it. My workflow at work has increased and become steadier, and at the end of the day, my hand no longer feels hurt or fatigued.
