This is a good sized vacuum sealer. The unit comes with 15 plastic bags to get you started and can be used for both dry goods, and for items such as meat or fish.
Dried goods are very straightforward. Simply bag the contents remove the air and seal. This is ideal for a range of items but I have found it to be particularly useful for coffee beans. When left in the air they go soft and loose flavour, this is a great way to retain that flavour.
For items like meat and fish the process is a very similar. You just have to be careful not to draw the juices out with the air. It is not difficult, just requires a little more practice.
Looks wise the unit is great. Its easy to clean and is better from a hygiene point of view.
