Ineffective design
It may be just me, but I tried every cylindrical up my nose that was in this packet, and none of them improved my air flow at all. Luckily, this was an inexpensive experiment. I have a design in my head that I believe would work, but I haven't been able to find it already manufactured.<br /><br />Basically, these fairly long cylinders are, well, longer than they are wide. They don't push against the nostrils so much as push against the part of your nose that meets the bone. This results in more of an "ow" than an "ah" experience.
