This sealer is the most surprising product I've used in a long time. Everything about it is different from the typical food sealer.  It's alligator-esque hinge.  It's double (game changer) seal. The added air valve is a new feature for me too.  Love that!  All that aside, what impressed me the most is that about a week after this arrived, I received a letter in the mail from the manufacturer that was called Guide to Consistent Sealing Results.  Which says to me that they really care about the customer experience, and want to make sure they have the knowledge to use it in the most functional way possible.  I know that all sounds really cheesy, but to me, that says a lot about a company in the best possible way.
