My Chalice Days were within a very short time period. While they earn the title of tootle puffer heaven to many folks, unfortunately as a dedicated DLH vaper the Chalice II and III atty's were barely used before they and their Reos (some bought specifically for them) were delegated to the out of service stash a long time ago. I'm not sure now that all three of the Mini 2.1's were even used at all. A bad case of Reo Fever struck... again.
