got the granberg and gave it a try. except for a cpl of the locking nuts on the adjustments being hard to get at, i think it will be a nice little tool. even on the 1st use and taking time to mess w/ the settings, it was a quick process. i think once i use it a few more times, i could probably sharpen the chain in the time (ok, maybe a little longer) it would take to remove it from the saw to use the grinder. only real issue i had was, when filing in one direction, the locking screws that hold the file in hit the screws that hold the guides against the links. occasionally, when the 2 came in contact, they would sort of 'jam' into each other and bind. i just had to try and make sure i shortened my file stroke a fraction.
still will have to remove the cover periodically to clean it out anyway, but for 1st use, the granberg looks good. cut good too afterward...better than if i tried to file them all freehand.
