Kensington Orbit Trackball Mouse with Scroll Ring (K75327WW)

I've purchased two of these over the years for home and office desks and this trackball is my go to. It is comfortable and practical for the price, as cheaper trackballs without a scroll wheel are a little irritating. It also doesn't take up too much desk space either. If there it one area for improvement I'd like to see Kensington make - it is that the scroll wheel after 2-3 years of use does tend to accumulate skin cells due to the type of rubber it uses, (this is a common issue with this type of rubber, similar to the sticky issue of some tablet pens). Using a different type of rubber would really improve this design.

Paso muchas horas editando video y los mouses o trackpads me acaban haciendo daño. Llevo más de un mes con este y aún no he sentido esa sensación. Puedes configurarlo para cada app y, aunque al principio te sientes un poco torpe, no tardas mucho en acostumbrarte. Lo único que me arrepiento de no haberle invertido al inalámbrico.

Poco pratico.. se sei abituato con il mouse.. l’alternativa con trackball è, ha mio parere, problematica.

Excelente produto. Depois que passei a usar, minha tendinite (devido ao uso excessivo do mouse comum) melhorou muito. Este modelo, com o anel de rolagem, que permite rolar diretamente as paginas no navegador sem precisar procurar o canto direito, faz toda a diferença. Lembre de rotineiramente retirar a esfera para limpeza, pois ele vai ficando mais pesado quando a sujeira acumula.

It was surprisingly easy to get use to. And is also reduced my wrist and shoulder pain from a normal mouse.
