aiyoh missed kam's qn
motor pump: i used till EOL (end of life) liao so i got a BN from WTS, then pass to my sis, she used it till EOL soon, but havent die. so i got her another rarely used from WTS, so technically both still working
manual pump: i have 4 from my elder sis, and i got 2 more BN from WTS when i was expecting my boy. turns out her pump working fine (didnt mind sharing) so i continued using hers and kept the 2 in storeroom, for #2 lar.
remember i pump exclusively so i will have 1 set at home, 1 set at work. no need to lug stuff ard mah
