Ah, by the way, about "sucks or not", I know it wasn't really meant for ECB, but it sucks in some other domains as well. (its Z axis regulation tool is just inaccurate enough to make adjusting Z0 height "manually" by looking at the tool over workpiece more efficient. Its pressure sensor is insensitive just enough to retreat the tool right -after- the bit got broken. Its suction pipe is placed just high enough to render the recommended home vacuum cleaner useless at removing filings. Its vise holds just weak enough to let the workpiece loose when 80% of the work is done (now I secure it extra with duct tape) The wrench to secure the workpiece is just loose enough to get your hand hurt as it slips off the mounting screw before you secure the workpiece. And there are many more such "just enough not to", everything 20% better and it would be a great tool, but everything is "not quite" and not only when it comes to ECB...
