A quite nice food vacuum sealing machine, complete with a built-in food scale. It has modes for wet and dry food products as well as sealing without vacuum. It also includes a digital food scale built into the left side of the unit. The scale operates on 2 AAA alkaline batteries. It works very well. We bought this unit to replace our 10 year old sealer that is no longer doing a good job. We like this one a lot.
