I used a similar one in the US ( Urobiolgics) and it cost me $275.
They told me I was having a Boy. and so did Intelligender. I was devastated after recieving the results because we swayed for a girl. But accepted that it was a boy.
Then at my 12 week scan i was told my nub shot looked girly.
I'm 32 weeks now and 6 ultrasounds have confirmed I'm having a baby girl.
Dont waste your money on these tests because after hearing so many stories about bad results you'll probaly only end up second guessing your result too.
also be VERY careful listening to people who claim these tests are accurate and have only posted 1-2 times on this forum - they usually work for the company
