Help, please! I just got my canisters from Amazon, and I am not sure how to tell if they are sealed enough. I have the 550, and I was able to seal the large canister enough so that I couldn't get the lid off - and heard air hiss out when I pushed the gray button on the lid...but how much is enough? I never had the light go on on my machine.
(I lost my manual...can you tell? )
Thanks a lot - I'm excited about using this feature for the Food Saver...correctly!
(And by the way, besides salad, what else can I use these for? My regular Rubbermaid canisters are fine for my baking supplies, so I wouldn't use them there.)
