I've worn one for years...
If I get sick, which doesn't happen much, I get the mildest version of whatever crud my coworkers get. It'll be just a tickle in my throat, a very slight headache, slight ache all over, and it's all gone and done in a day or two. When I take the q link off, because someone convinces me I've been conned, I get a big nasty, long lived illness, almost immediately. So (shrug) that's my story....
