I have owned a foodsaver brand model for about 4 years now. I was very excited when I bought it. We were boping to freeze garden produce and leftovers, among other things. Right after I bought it, we went to the farmer's market and bought abought 5 dozen ears of corn, hoping to freeze it. We cut the kernels off the cobs and tried to use the food saver to package it. It was then that we realized that the moisture from the food prevented the bags from sealing. This is the downside. I'm surprised that nobody has mentioned it. If anyone knows a method to vacuum seal foods with liquids, I'd love to hear it. I had high hopes for this gizmo. Also, like many of you, I use Mason jars to store things.
