I am glad I got this container. Whenever I made salad dressings in the standard container it would splash and go all over.  But in this Aer Disc container the liquids don't get splashed around but are sucked through the disc.  I love it for salad dressings.  Have yet to make smoothies in it but will when it gets warmer.  We don't consume mixed drinks so can't speak to that either.  But I am happy with my purchase.
