Title: They leak. A lot.
Review: These bottles leak. It doesn't matter how you assemble them, or if you assemble them wet, or dry, or in space, or in a cave. They leak. Terribly. And Avent knows it. They will even replace your leaky bottles if you call 1800 54avent. Of course the ones they replace it with also leak. Buy Dr. Browns instead.
