Iv had a vacuum sealer machine for a while which I use to seal foods to put in freezer.Iv often wondered about cooking this way So was excited to see machine.I used same day I cooked 2 steaks and vegetables after cooking I seared steaks to make them look better.They were so nice the juiciest sifted steaks have ever eaten and the vegetables tasted so fresh.Does take a while to cook but so so worth it.Great buy
