2nd hand breast pump

Typically 2nd hand shld be ok if it's still working fine. but need to change some parts. and for spectr, definitely the flange because size also varies depending on yur nipple size. For me I can't even use the default one they give as it doesn't fit well. It needs to be fitted well, not too tight or too loose so tt u can have good suction. U can find different sizes on shopee. Also the backflow and valve may need to buy dependingon the condition. If it looks fine u wld definitely want to just do a thorough wash and sterilise one time before the first use. The tubing is fine to reuse.
