How do these companies come to that conclusion? I think most people start to smell after only 24 or 48 hours max so how do these companies get 72 hours out of their testing?
Im assuming they’re fudging their numbers but at what point does it become false advertisement?
They utilize a type of metric that you usually obtain by pulling it out of your ass.
Plot twist: They spray it in their ass and check to see whether it’s still there 72h later
That would indeed be the ultimate test.
