Here is my honest review after suiciding with this script for more than 48 hours:
The bot will runs smooth but pretty slow. The camera movements will often make it confuse itself and will need someone to re-position the camera to make sure the bank/stairs/or loom is seen. For some reason over time the bot slows down and stops working independently, for the first few hours it will run 1k flax per hour, but 2-3 hours later that number will go from 600 down to 460 per hour. I hope this will be looked at and fixed in the next revision.
