We've had this for a couple months now and would have returned it if we could but turns out we aren't allowed. The capacity turns out to be small because it doesn't do well when filled up so can only be filled about 2/3 unless you're only using liquids (i.e. no powders, frozen items, etc). As well, my wife has had trouble getting it tight enough to not leak, or to loosen it when I put the cup onto the blade.
If we were to do it again we would have just bought another pitcher.
