I bought this device a while ago and tried to calibrate it then and could not get it to properly and have just tried again and had little success. Please see the video of me trying to do it here and you'll see that there a big spots on the page that are blocking the movement, and i have to turn the device all the way around to be almost perpendicular to the screen to get it to register at the edge of the screen. It moves very 'messily' and times out before I can finish the scanning of 80% of the screen.
Great if you can help otherwise I might have to keep this in the 'nice idea' box. It would be amazing to get on a screen sharing call to show you what i mean and help me figure out whats going on?
Thanks in advance
