I have tried nearly every brand of breast pads and found these to be the most effective, comfortable, reliable and best value for money.
They are absorbent and plastic backed (so do not leak & feel dry when wet). Yet are still soft & thin enough that they can fold with your bra, so they don't fall out when feeding like I found some of the more expesive ones would, and cannot be seen through tops/bra. The sticky is pretty good, but not the strongest compared ot other brands - I just found putting the sticker towards the bottom of bra worked best for me.
Great for when applying nipple cream (avoids staining your bra) and day or night use.
Invididuall wrapped handy for nappy bag, and I just recylcle the plastic individual wrap.
Affordable enough that I was happy to change them frequently and wear often for piece of mind when heading out.
