I tried to pretend this thing worked so my wife wouldn't thing I'm an idiot but the truth is, it doesn't. First, the bulb sticks inverted if you push it all the way in, you have to push in 3/4 of the way or unscrew it to push the bulb back through the other side. Second, the suction only works if you've got the perfect angle and a complete seal - both of which are incredibly difficult to achieve with a screaming, squirming 6 month old. Ultimately we find ourselves using the hospital aspirator and a q-tip to do a proper job. The good news - my 3 year old thinks it's a really fun "toy" so it's his now.
