This is a very compact vacuum sealer designed to take up less cabinet space than the standard ones for people who don't need to seal large items.  It uses 8" rolls of bags and can seal ready made pint or quart bags.  If you are sealing a few small items such as burgers or fish fillets it will serve you well but if you want to seal larger items like big steaks or chuck roasts you will need to get the larger versions.  It seals well every time and is easy to use.
