I got the Costco pack, and to tell you the truth I'm only on my second one and that was over 2 months ago. You'd be surprised how much those suckers can put in. If it gets a little full I just push down a little harder when I do the back and forth and that works. The trick is the right amount of pressure and short quick strokes, but you kind of have to hear the rotor things move. If you don't, you aren't pushing down hard enough.
