I've tried every way I could find to store leftover guacamole (I'm the only one in my household that eats guac), but nothing has worked until now! This product performs exactly as described. I was skeptical when I bought the product, but wanted to give it a try. I was so skeptical of the product that my first batch of guac was a small one (only used two avocados). After 36 hours, it was just as fresh as when I made it! I would recommend this product to anyone who enjoys guac! I can't wait to buy more avocados and make a larger batch of guac!
