The pink handled test is called SurePredict and they are the brand I swear by. With all my losses I get a line on them a good day before the FRER. Bad new with them though is they are really really good at detecting chemical pregnancies. I have seen lines on them from 7dpo on, but they never show a line for me when there isn't hcg testable in blood.
If it helps if I test every day from 7dpo on, my first indication is normally a thin line on them. Then on subsequent days it thickens and darkens pretty fast.
