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

i hoped for the quality of the company (recommended), it turned out that in vain. the first track ball broke as a result of an internal electrical failure (something shorted out, the computer rebooted and the ball died). the second (as it turned out, all logiteks) after 2 months. the left key began to fail: you press once, it works twice, you try to press two - it does not work, you hold and move the object - it spontaneously releases ((( in general, a quiet "horror"! disappointed with logitech, although i was ready to buy something a little more expensive, but more reliable, albeit with the same functionality. although the trk-ball is made really convenient and ergonomically. i was especially pleased with the large ball. its a pity the assembly and materials turned out to be.
