Morning mommies!

So yesterday a friend who is currently expecting exactly the same time as I, told me she had used IntelliGender to predict the gender of her unborn child (we are both 16 weeks). She said she used it with her first and it was accurate. She used it again this time and she believes it's accurate.
So curiousity got the best of me and I also purchased it and did the test at home. I'm so excited about the result and in my heart of hearts I believe they are accurate but I also want to wait for my 20 week scan for my Dr to confirm before telling the world and hubby (the gender is exactly what he wanted)
I have read testimonial on their site and nearly all the women that have used it (some even for all their multiple pregnancies) swear by it. Basically 90% say it's accurate.
Has anyone tried it here? With this current pregnancy and those before?

Secondly, there is nothing you can pee on that can tell you your baby's sex. I can mail you a box of baking soda to pee in and it will essentially be the same thing. It's just an expensive guessing game with a 50% chance of being right, like every other old wives tale. Why not go with the Chinese test? At least that's free and not a waste of money.
