Have used Food Saver for years. This product is easier to operate and does a better job of sealing. I like the 'softer' vacuum setting for softer foods. It seals perfectly every time. Not had to re-do any of the jobs I have done with this machine like I did with the other.
It is not small, Does take up counter space. With the built in bag roll cutter it's wider but I don't need to make space for a seperate cutter.
