I was VERY pleasantly surprised by how well the Genie worked! I now have my brown sugar, powdered sugar, several home-made soup mixtures, and rice, all in vacuumed sealed jars. I need to get more jars, and keep on sealing. It's literally an item I'll NEVER regret buying! And the supporting emails they keep sending to help me use their product, are exceptional. I really do appreciate it, and have no problem leaving a five star review.
