Chiro,
Mine pump is PISA US set bought in 2011, so far so gd for me, I even passed to my friend to use early this year. Need to use a transformer for the adapter to change the voltage from 110V to 230V. For BM storage, I used both the cups and milk bags. Cups are for the fresh ones I refrigerated, and bags are used for stashing the excess in freezer.
Iko,
I gave up on latching after 1st 2 weeks bcos bb could not latch properly and I got injury and bleeding problems. I pump exclusively on PSIA after that. Have to be hard working from the start. Even u see not much milk dun give up. Set up a routine like pump every 2 hours , whether u have urge to express or not. Try to pump longer oso, even u think no more to express liao. Our body will produce more upon demand. Drink more water. I think gd diet oso plays a part, I realised during confinement, got more variety of food (CL cooked a lot), I managed to express more, subsequently, I just cook simple dishes (usually 1 dish with rice), milk was lesser a bit. Eat more fish if u can, I ate fish everyday during confinement.
