I bought a trackball in order to make it more convenient to use a computer connected to a TV. But I quickly got tired of it. I don't need a computer on my TV. The trackball moved to the table behind the computer, on which I sometimes work, but mostly I surf the net, sometimes I play. In normal use, the trackball proved to be excellent. I got used to it in a couple of days. Now I connect the mouse only in order to play counter with a friend once every couple of months. The rest of the time I use the trackball. It takes up little space, it does not need a carpet, it runs on a single battery. Thanks to Unifying technology from Logitech, several more devices can be hung on its receiver (a gaming mouse, in my case Logitech VX Nano and a wireless keyboard). The ball has a small inertia and, for example, to close the program, you can roll it to the upper right corner and it will travel a short distance by inertia. It seems like a trifle, but you quickly get used to it. The positioning of the cursor compared to the mouse is no different. I tried to play the same contra - I didn’t like it, but it was probably not created for this. I've been using it for about half a year. Drivers show that the trackball will work for another 478 days. And this is from one AA battery, which was included in the kit ! Tried to draw them in SolidWorks. Quite convenient. There was no desire to take the mouse, even though it lies half a meter away. The device in my opinion is almost perfect. To make it perfect, it lacks Logitech's proprietary inertial scroll wheel. I hope that someday the manufacturer will release an ated model (this one has been on the market for many years) with an inertial wheel and I will definitely buy it.
