Two cursors at once (as the name implies). In some details they are similar, but basically their unifying element is a dark style (after all, in terms of contrast, they are very different in fact). Despite their simplicity in visual terms, they are not devoid of such qualities as, for example, convenience.

They weigh relatively little and support stable operation with all current versions of Windows (take versions 7, 8.1, 10 or even 11). Install and check whether they are suitable for you or not.
