Hmm, honestly belum pernah dengar jenama Ms. Tellme ni, and none of my mum friends pun pernah mention it, usually kami pakai brands yang lebih established macam Clearblue or First Response. Kalau you're thinking nak try, maybe safer to go with upt strips yang lebih terkenal and widely available kat pharmacies sini, sebab kan upt is quite important decision making thing kan?
