Just bought, seems to work alright thus far. 
  
Will update with a proggy later . 
  
edit: Ran into a slight bug - pick-pocketing men at Lumbridge castle, when it had to go get food it went upstairs to the bank and then immediately went back down to continue pick-pocketing without even opening the bank. 
  
I stopped it the second time I saw it do that 
  
  
edit 2: spam-click the pick-pocket option is irrelevant on the GUI, it spam-clicks either way. 
  
edit 3: pick-pocketing H.A.M. members - if you get caught, it doesn't walk back to the place if you get thrown out/locked in the jail. 
 - Doesn't drop items when inventory full either, just keeps trying to pick-pocket.
