Looking for 2nd hand Doppler.

Sis, I get it, dopplers can be pricey! Honestly, maraming mums I know nag-try ng 2nd hand from Shopee, pero make sure talaga na may warranty pa or tested na working nang maigi before you buy, kasi ang frustration kung hindi accurate or defective agad. Better pa rin kung nakaka-afford, mag-invest sa bago from reliable sellers kasi ang peace of mind, especially first time mom ka pa lang, pero if tight budget talaga, just be extra careful sa reviews at seller rating ha? Either way, best pa rin na i-confirm everything sa OB mo, kasi ang doppler ay tool lang; your doctor knows best kung kailangan mo or regular check-ups lang ang kailangan. Good luck, mama!
