the upgrade kit made a huge difference in clogging and static build up from v1. That said, I don't think people should have to pay another $30 to fix their original design flaw, especially since that grinder is over $200.
This kit takes effort to install as some of the screws are really hard to manipulate. Also, the plastic guard they provide is HORRIBLE. DO NOT INSTALL IT. JUST STICK WITH THE METAL PIECE ONLY. You can find more information on this excellent video:
