Query: WHAT A JOKE!!!

We bought this food sealer in hopes of freezing left overs and not having freezer burn...We would be better off buying a store brand freezer bag!! We have had terrible luck getting all of the air out of the bags. You have to help the machine by pushing the air upwards while it is in the vacuum mode, and still all of the air doesn't come out. My mother has a Tilia brand sealer and swears by it, I think we will spend a little more and save ourselves the time and frustration. DON'T WASTE YOUR MONEY on this product!
