I have one and I use it all the time for food. I think it is overkill for cigars, unless you vacuum them for long term aging to reduce airflow. For bombs and trades it is overkill. Just kill it manually or you will squish the cigars like everyone else has said.
I use it all the time when I buy hamburger in bulk and freeze it. It works great for freezing things. Also you are supposed to be able to store individual portions in there and cook them in the bags in hot, not boiling water. Tried it once and it worked pretty well with a salmon fillet.
