I'm sure they have magic Himalayan pixie dust in em or some such (please note - that's sarcasm and I'm sure they have some proprietary formula for making these things), but that doesn't make them worth $40 IN MY OPINION.
Equivalent simply means roughly equal to, not exactly the same as. You can buy a douche that does similar to what the Genselect douches do for less than $5. And actually there are baking soda douches for sale on the market for less than $5 (in addition to jellies) that can sway for a boy, so it's not true that you can only buy vinegar and water douches. Massengil sells three different formulas, one of which is baking soda. $3.47 http://www.drugstore.com/massengill-...6-oz-/qxp26528 I personally don't recommend them because I don't believe douching to be safe or neccesary, but they ARE available.
If you REALLY believe in your product and REALLY believe that it gets 96% success rate, then you have nothing to fear from me, I'm one person and a product that is so amazing and effective will speak for itself. Bill Gates doesn't take time out of his day to hunt down people who say "Windows sucks, use Linux" on minor message boards because he knows his product is preferred by most. ;)
Just in the interest of providing accurate info to people, Genselect does NOT track the success rate of their client base http://www.experts123.com/q/what-is-...customers.html and so the 96% success rate that is oft-quoted is NOT what their customers are getting. The 96% success rate that they claim, is based on one study dating back to 1999, done in a country notorious for early gender-based abortions and IN MY OPINION that fact alone sheds doubt on the results because we have no way to know how reliable this data is - for all we know, couples could have tried 10 times to get their DG, kept that info from the researchers, and only reported the successful attempt. You can read that study for yourselves here. http://www.genselect.com/goodnews/Pr...nicEquilibrium
