Review on Logitech Trackman Marble Trackball Mouse - USB Wired Ergonomic Mouse for Computers with 4 Programmable Buttons, in Dark Gray - Improved SEO by Danish Danish ᠌

This is my first trackball device. So there is nothing to compare with. But summarizing personal experience, I can say that this particular implementation of the trackball is convenient. To the question of trackball vs mouse. For myself, I did not find significant advantages of the trackball over the mouse and vice versa. This also applies to the accuracy of cursor positioning, and the speed of work. You can equally well highlight the contours of objects in photoshop and play shooting games online with colleagues :) Almost everyone writes about the need to clean the trackball and wash the ball with soap. Some people wash their hands on the occasion of the start of work with the trackball :) My personal observations: - 3 ball bearings require wiping with a finger from plaque once every few hours. this is done very simply and takes no more than 10 seconds. - the ball was washed with soap only once and abandoned this idea. This is due to the fact that this procedure sharply increases the coefficient of friction of the ball against the supports and completely deprives the ball of the ability to rotate by inertia.
