I haven't had any problems with leaking as others have stated. After you fill it, turn it backwards until it naturally sets into the grooves and then twist to tighten. I don't understand why the plastic comes up so high and it couldn't just be the base. There are actually holes in the base of the lid so nothing would be held in the lid if it did leak. I am a fan of Vitamix but this does fall a bit short.
