Lullaby are very prompt with their order, dont know how but i even got mine very quickly which considering where i live is amazing. ive havnt used them yet.

Ive used Ovunow ones and havnt had any issues with them (i have with the HPTs) as well as the ones from the supermarkets- fortel, cant think of the other one now.
I usually double check if i get a faint line with cheaper one, then i cheap with a more expensive one. I just love POAS i think!

Good Luck
