I have a Food Saver. Called to replace the o ring that helps maintain the seal. They said it was on backorder. I said OK I can wait and they said they could not accept an order for anything on back order. Sad part is the machine is rather cheap but the BAGS are expensive.
I do see there are aftermarket bags that others recommend. I will try several brands with rice to be certain. Save the wet foods for the name brand bags ...
