The close-out date for joining the group buy has not been set so there is still room for more people. Scott said you may now go to the Stromung website to place your order. BE SURE TO NOTE "R3vLimited Group Buy", QUIET or standard AND the tip preference.Last edited by Stan; 03-14-2026, 04:15 AM.👍 3Comment
