Ergonomics features of finger operated trackballs I have not used peripherals with wires for a long time, so the support of 2.4G radio channel, which is not affected by Wi-Fi plus Bluetooth as a nice addition, left no choice but to "shut up and take my money". The bottom line is that when I saw a new ProtoArc model on AliExpress for my index finger, I was again drawn to try something new, especially since EM03 is already a more authentic trackball that does not resemble a "mouse with a ball on top". For the ProtoArc EM01 manipulator itself (see our review), I had almost no complaints during the year of use, and everything turned out to be good in terms of reliability, except for one point, which I will talk about a little further. Then I chose the EM01 model from the little-known manufacturer ProtoArc, and in principle, although I did not experience any euphoria, but I got used to performing the same actions with the new manipulator just as easily, and now I think that you need to buy your first trackball thumb operated trackball - it's really easier to adapt, because scrolling the same and the location of the main buttons is the same as that of the mouse. Review of Protoarc EM03 - trackball for the index fingerĪ year has passed since the day I decided to switch from a mouse to a trackball in search of new sensations.
