Like most things it's probably 50/50 at best. Good to do for fun but I wouldn't go out and start buying pink/blue items based on the results

I got one of these, and it turned out to be correct, but I wouldn't start buying any baby clothes until you have that gender scan!!

If I knew for a fact that it was 100% accurate - a sure thing - I'd not want one. I don't want to know for sure...but I'd like to be do the test to see if it works...does that make sense? Or am I just odd? ;oD
