I have had a Vevor dz-260c for a few years now and I think it is a good unit. Sealed lots of meats, some vegetables, and 5lb bags of flour that I freeze for a week to kill the bugs and then can store them on the shelf for a long time. https://www.vevor.com/chamber-vacuum-sealers-c_45389/chamber-vacuum-sealer-bag-sealer-320mm-vacuum-sealer-machine-commercial-dz-260c-p_010745143510#mce_temp_url#
