I love this machine. It comes with some free seal bags and the machine itself is light and easy to use. It has 3 functions, vacuum sealer, half and sealing only. You can use it to store food to keep longer. You can just use normal plastic bags which you can by from any shops. It is very useful if you buy a big piece of meat or fish and want to use it for a few times. You can separately store them in a few bags, sealing with this little machine. Very happy for the purchasing.
