I've had the aer disc for over a month and though I like(d) the idea it really doesn't work all that well for anything. I though it would be lovely for froth on coffee 1) it's way too big to froth a small about 2) it won't froth nut milks but none of the frothers will do too well at least according to all the stories.  It's way too big to make mayo unless I want to through 3/4 of it out and I'm not willing to do that.  I asked about a 32 oz jar and they obviously have a big family if they think that a 48 oz jar will take the place of a 32 oz jar. Wouldn't waste my money again.
