Query: Leaks!

I was skeptical when reading other reviews about this cup leaking. I ordered it anyway. This cup leaks all over the place! Trust me and save your time and money. I read the directions and took the time to make sure the seal was assembled correctly. Guess what? It still leaked. Leaks out the vent hole and around the mouth piece. I am sending these back today.
