I bought one the very same day they hit the shelves! I was only about 11 weeks then I think and had just "known" since I found out I was pregnant that it was a Boy - The test immediately came up BOY - My 20 week Ultrasound confirmed this So it worked for me! I did alot of research on the product before it came to Aus and decided to go ahead and try it, just for fun! I didn't run out and buy Blue until after my 20 week Ultrasound... I think if you're not going to take it too seriously, go ahead, there are alot of success stories that it has been spot on with and a few it hasn't - Like everything in life! Works for some, not for all... If I were you, I'd be going for a gender scan instead/as well

Good luck!!
