I was disappointed in the oracle ones. I didn't get a BFP until 13dpo and even then it faded to nothing when it dried. The BFP on the FRER from the same urine sample was clear as day, even after drying.

A friend recommended the inpregnancy ones (ebay), but I haven't had a BFP since buying them to test them out myself. Her only criticism of them was that they weren't at their darkest until 20 or 30 mins after testing. Of course, she is pg with twins, so she might have gotten an early BFP with any brand...

All the Americans I speak to rave about the Wondfos lately, but I don't know if we can buy them here?
