I think to send as sniffies in order to get a "rough" idea of what a scent smells like OOB, it usually is fine. Also, to get a "rough" idea of what 2 or more scents "may" smell together as a blend, it's a way to get a "rough idea". I only do B&B, so for me, it helps when I want to come up with fun blends. I know that a FO in application often smells much different(& sometimes totally different) than OOB, but I'm weird in some ways: if I HATE a FO OOB, 90% of the time, it gets thrown in the box of oils I don't use. I know that's not fair to the FO( ), but it's ok, because I have way too many FO's to begin with! But yea, IMO, the whole Q-tip thing is really for a quick whiff to quench your OOB curiosity(& sometimes works to trade sniffies, especially if it's a really expensive oil & someone can only spare a swab).
