I can tell you that the device certainly has parallax even though it might be reduced by a lot. Most importantly though the pen tech is sorta broke in the way that when pointing with it the cursor is offset around 1-2mm from the actual tip. This can mostly be solved with calibration however after calibration if you tilt your pen in the opposing direction from the one you calibrated with the offset is REALLY bad like i sort of hate drawing with it.
