Bluetake BT510 Bluetooth trackball

Bluetake’s BT510 Bluetooth trackball is one device that will take some getting used to. We recommend that DTP artists and hardcore gamers stay away from this device, as it doesn’t offer both speed and precision simultaneously for even the most menial of tasks. Trackball usage is mostly limited to those who have scarce desktop space, or factory machines. On the upside, it has a convenient battery charging dock and build quality is excellent.
