I completely and totally understand everything you're saying here.

I never test anything before I have to go to work. I do not want to be trapped wearing something I hate all day. :( I only test at night or on the weekends.

I don't work in close quarters with anyone or with people who have said they have perfume allergies, so I'm not as worried about that, but I hear you re: smelling up all the scarves and suchlike. :) I got a Vivofit at Christmas, and I have been very carefully avoiding scenting that wrist so I don't permeate the plastic with scent.
