I was skeptical, everyone I know uses the bulb one you usually see/get at the hospital. One friend told me she swears by this so I thought it wouldn't hurt to try. I left it unopened for about a week until one day I could not get this one booger out, I tried suctioning it out like 7 times. I opened this and got it on the first try!! Now I keep one in baby's diaper caddy. Easy to clean and effective.
