Last time I bought an Adesso trackball because I felt Logitech was overpriced ;but regret my choice in doing so. The Proto Arc trackball on the other hand feels and works great, on par with Logitech for sure. The option to use wireless with dongle or Bluetooth is a bonus and makes this purchase that much more worth it. I can't comment on battery duration yet ;but will edit my comment if the battery is atrocious. Read more

This is a brilliant mouse. The ball has a nice smooth glide action coupled with accurate pointer movements. It is very comfortable to use and the tilt action makes it even more comfortable. I thought it was a bit of a gimmick when I read it in the advert, but having used it for a month or three now, the tilted angle is the most comfortable way to use the mouse. The connectivity is good and you can still use the mouse whilst charging. So there shouldn't be any down time. Read more

I was looking for a good vertical mouse to ease the strain on my shoulder. This mouse fit the bill perfectly and I love the fact that you dont have to move it around, it just stays perfectly in place next to my keyboard and I never have to worry about running out of space to move the cursor. I have a standard (non-trackball) vertical mouse at work that is worth over twice as much as this one, but I like this trackball mouse a lot more. One of the best home office purchases I have made. Thanks. Read more

Really great product Read more

Rato de muito boa qualidade. Ao fim de 6 meses de utilização nunca mais tive dores no pulso. Cheguei a pensar que, por ser trackball que provocasse desconforto ou dores no polegar, mas nada disso. Tem uma ergonomia perfeita, botões silenciosos assim como uma adaptação extremamente rápida. Ao fim de 2 dias já usava o rato de uma maneira perfeitamente normal e natural. Recomendo vivamente para quem costuma ter dores no pulso ao usar o rato durante muitas horas por dia. Só não recomendo para gamers e edição gráfica, mas para trabalho de escritório é o ideal.

Coming from Logitech MX Master 3S and a first time Track Ball mouse user, this product is amazing. It takes some time to get used to but this feels great in the hand. The built quality is a tad bit less compared to MX Master but at least it doesn't have the rubber coating that MX master have that disintegrates over time. Very good value for money plus the amazon discount! Read more

Good quality. Takes a while to get used to after using a “traditional” mouse. Glad that I made the change… Read more
