Question: Title: Won't maintain vacuum over an hour or so Review: I had high hopes for these containers. Of course, there are plenty of things you can do with them if they work. I initially noticed a problem whan I would come back to the container and the lid removed too easily - no vacuum. I did the (marshmallow) test and, sure enough, the container would attain the vacuum initially but, after an hour or so, it would lose the vacuum. Even though they were new, I did all of the tips and tricks posted on the Tilia web site (cleaning around the rim, making sure there were no crumbs, etc.) Nothing works. Really disappointed. I love the foodsaver and really wanted to utilize the canisters. They just don't work. Does this product review convey a negative or positive sentiment?

Question: Title: Anticipation far exceeded actual product Review: What a disappointment! The picture quality was fuzzy (at best). Perhaps of a less troubling issue, the sub titles were in Japanese. The English sub titles were available and were presented on top of the Japanese. Even though this is one of my favorite operas, I returned it.
