I absolutely love this vacuum sealer! Most importantly, it seals very well.  As with all sealers, when you are doing bags you do have to get the bag in the right spot for a proper seal.  I sealed nuts, cheese, and also meat, and all worked perfectly.  This is going to make my freezer so organized and save a ton of money.  The instructions were easy to follow, and I love that you can use most any type of replacement bag.  It is well made, and very sturdy.  I highly recommend this sealer.
