Overall, I like the product. The one concern I have is sometimes two of my container tops (and I have quite a few containers) won't hold a seal for longer than a day. It doesn't happen all the time, which makes me think perhaps the rubber seal in not completely cleaned when I return food the containers. Even with this small hiccup, I'd recommend the product to family and friends. It's great, and I use the products and the vacuum machine everyday.
