I have heard that these can cost quite a bit, and you know, I went to the Chinese Gender Predictors on the internet and they were successful on predicting my childrens genders both times, along with 7 other people here at work. So far, it has a 100% rating with me and my friends, and it is free. I don't know how it works, but so far, it does. Not one person I know has disproved it yet. Plus, you can find out the gender from an ultrasound as early as 16 weeks, if you can talk your doctor into itthat early. If it were me, I wouldn't waste the money. Good luck!
