Do they use standard food saver bag? I have been using foodsaver for years, but have found they lose there seal sometimes.
I have a box of food saver bags and have used them with the Weston Pro 2300. It seals the bags great when sealing Tri Tip, Flank Steak, and Pork Butt. It has been hit and miss sealing Baby Backs. I have read that the foodsaver bags suck when using this sealer and I will probably just buy Weston bags from now on. From what I have read they are thinner and seal better.
