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

this model is generally some kind of designer prank or joke. completely unusable design. from the word at all. the absence of a "hardware" device for scrolling is solved by shamanism with special software, after which an action that you don’t even think about in normal devices and do on the machine is performed here using a cunning manipulation to hold the side button scroll the ball. to do this quickly, you need to pump this skill separately. well, the symmetrical side buttons will fit well in the hand only of the ninja turtles, who, if anyone forgot. three fingers. for a representative of the homo sapiens species, such an arrangement of buttons does not allow doing anything at all in a normal working rhythm.
