"excellent seal a meal!"
I read instructions, practiced without food, made jam and sauces and sent them overnight by post to family.Be patient and caring it really is an excellent tool. like anything RTFM (read the flipping manual/instructions). I have since used it to freeze excess fresh garden produce including soft fruit. Some are small others large packets. I will do soup in winter and am about to make individual meals. oh, and cooked or raw meat and fish work too. I do 2 and 3 portion packs. not much waste in the bin these days. Take care to cool properly if you are going to freeze. It is easier to handle if food is cool and the air is removed more effectively. i am so pleased I bought this gadget. Only problem is that the bags and rolls are not cheap but the cost is offset by food savings. Also the food will microwave in the bg too, (pierce bag first or you will have a rocket).
