Want a shake? Instead of running the blender, pouring it into cups, washing it all, what if you could blend in the cup? That's what you can do with this. It comes with two generous-sized cups, each with a sturdy lid with a drinking spout. 

If I had a negative comments it would be that these are a bit heavy and bulky -- but that's also because they are super-sturdy, clearly built to last many years. The drinking spout latch is very tight and hard to work and I hope will loosen up as I use it.
