I used to put all my frozen meats in plastic zip lock bags, but they would always seem to puff up with tons of air inside. So I got the NutriSealer vacuum which does a great job at completely vacuum sealing, and at the same time easy to use. The system comes with the vacuum sealer, 4 rolls of bags, 2 vacuum bags, and a vacuum attachments.  Focusing on the sealer and the roll bags, all you do it seal one end, cut the bag to the right size, put your food in, vacuum, and then seal. There there buttons on the sealer, SEAL, VACUUM. SEAL and VACUUM, so easy to press and get going. Gets the gets the job done. The system also came with two vacuum bags which is a nice add on. Overall would recommend.
