Man! Is this what you mean by "strip"!? I shouldn't have even bothered to look...! ;o)
I used to work for tis manufacturer as their Product Development Specialist--in other words, I worked very closely with the inventor and I think I know about this product better than most. Now, just to clarify; I don't work for them any more. It wouldn't benefit me any more than it would to you if they sell that products more so that's not my incentive. That being said, Breathe Right Nasal Strip is better than any other similar nasal strip product (and I can give you at least a half a dozen reasons why). I guess the only down side could be that it's probably more expensive than other products. Now, the question of "does it really work?" I knew Regina Jacobs personally (this was 1999 and 2000 right before the "incidence") and the company was looking for the athletes in Sydney Olympics to sponsor. I called her up and told her about this deal. She said that she HAD deviated septum but it was surgically corrected so she didn't think there's any need for her to try something like "Breathe Right". I told her that I'd send her some samples and she wouldn't have to use it if she didn't like it. I got a call from her literally next week (right when she received the samples) and she said she couldn't believe how well it worked! Now, is it really "working" or is it just perceived feeling? Well, probably more so for the latter. However, they were (now the company was sold to an European company) so sticky about "clinical study" that if it's not proven effective, they wouldn't market. With Breathe Right, there has been a research done that, with the strip, you can perform the same intensity of exercise with slightly less heart rate. This does NOT mean you will have improved VO2Mas, certainly NOT that you can run faster; but simply "possibly indicate" that you can perform that level of intensity "easier" and potentially "recover better". Personally, I really can't tell the difference when I wear it while running. What I DO notice is, if I wear it at night when I go to bed, I'd feel "better rested" next morning. Be aware, though; it takes something like 2 weeks before you actually get used to wearing it at night and you start to feel the real effect. So in other words, if you don't see any difference in the first couple of nights, don't give up on it. Another occastion I personally like to use it is when I'm on the plane. I do feel I can breathe much better and easier then (of course, if I fall asleep, person sitting next to me would appreciate that I'd snore less with it as well!).
What's more impressive, let me digress a bit here, is a Breathe Right for horses. Yes, race horses! In fact, I made the design for it and my name is on the patent for that one. Race horses sometimes bleed in their lungs and out of their nose. With this, according to the clinical study we did at North Carolina University (with a treadmill for horses), it reduced bleeding by whopping 80%! Swear to God, true story!!!
It's just a post and a product that does not work for everyone. It may well work for Cakeeater. He asked for opinions and experience and that's all I can give. It doesn't mean I'm wrong or don't know what I'm doing with a freakin' breathe right strip!
