Wah, RM39.60 is really good deal for oximeter lah, especially with the flash sale ending so fast! Honestly a handy thing to have at home, especially kalau ada babies or elderly parents, my mum friends semua pun ada one just untuk peace of mind when anyone kena demam ke or feeling under the weather, pastu boleh check oxygen levels without rushing to clinic immediately. Bagus jugak for pregnancy checkups if your doc suggests it. Tapi just make sure you're checking it's a legit seller from the link ye, and read the reviews first!
