i used the milkees milk saver, but only used it for a few days until my milk supply regulated. Every now and again when my baby will STTN or go a long time without eating and throw things off a bit ill pull it out and use it, but i got to where my letdown on the opposite side was less than 1/2 an ounce and just didn't seem worth it to me. I'd collect all day and only have around 1/2 an ounce. So now i just use it when i feel engorged. You could just use a tupperware or stick a bottle in front of the other side
