I have 5 complete Lact-Aids plus several extra tubes and rings. I also have 3 rolls of bags (I think there are 50 in each roll) plus a partial roll. I have two of all the other parts of the kit (funnel, syringe, etc.) I used these for 13 months with my daughter starting in May 2009. They have been used with both breastmilk and formula, but primarily formula. $65 for everything (shipping not included). PM me if interested!
