This unit is marketed for being ideal for sealing and storing soups and liquids. Other units are not ideal for this. So if you are looking to save soups you should seriously consider this product. That includes stews or things with lots of marinades. The other marketing concept presented is that you can store smelly foods like fish odor free. Other products are not designed for liquid rich foods. This unit has some reports of the lid breaking. You can get a replacement from the manufacture fairly easy but do not buy this if you are looking for the most reliable product on the market.
