I recently bought this thing and loved it. It's a little confusing figuring out the orientation of each part, but once you've got it down, you've got it down. I saved my guac for about 3 days and it was still fresh, green, and delicious. I've heard tell of people saving it for up to a week... Not sure I'll ever get to a point in my life that I am able to restrain myself from eating guacamole for a full week, BUT IF I DO!!!!
