I have been using a FoodSaver for years.   I use it almost every day.  This FoodSaver has a serious flaw.  It's very difficult to hold a package and push the bar to seal.   I have had many FoodSavers and have never had this kind of problem.  I thought it would get easier as I got used to it, but it hasn't.  My other FoodSavers have been very user friendly.  I would love to have one of them back.
