Has anyone heard of or used this ? It was in a email ad I got from Boveda and was wondering if anyone had heard of or used this Vivi for curing ? It says it takes it from weeks to 10 days with a jar and no burping. One of those " if it sounds to good " type things. Would love to hear any comments from the community on this or anyone who's used it. It's not overly expensive to try out but I'd still rather hear from you guys before plunking down $20.
