I finally gave this product a try. It was very easy to use. I purchased 2 rolls of heat seal packaging so I could make custom size packages. I packaged about 40 bags of uncooked rice that I bought in bulk. I packaged various amounts for different uses, marked each with the date, cooking instructions and cooked yield amount. Easy peasy. I can see using this appliance for a lot of different things, including stocking our RV for trips without having to find room for full size food containers.
