This was surprisingly easy to use. We were able to vacuum seal all of our frozen meat items from our grocery order. We ordered bulk and seperate everything out. Took us about an hour to package everything seperatly and label it. Really easy process. It came with 4 rolls of the bags which is a ton honestly. Only take ten seconds or so to vacuum and seal. This is going to be such a great asset to our kitchen and help us prevent waste thus saving money.
