I can't stand the lead feed on this pencil. You have to remove the cap, twist it, press the end to push out some lead, turn it back, replace the cap and then twist the cap EVERY TIME YOU WANT TO EXTEND THE LEAD. So inconvenient and it doesn't work perfectly, it takes fiddling with to get it to work right. Guess it is back to the drawing board to find a pencil that feeds in a simple, usable way.
