It works...for awhile
I got the 1 cup model, I think the first time I packed it, the little spout thing broke from the container part, I rigged it enough to work, then the gasket started failing after like, 6 months. it would spew steam out the sides no matter how hard I screwed it down.
The clincher was this, it has a LIFEIME warrenty, but after 4 emails to the company..they NEVER replied
The product is a good idea, but the company customer sevice is non-existant
