I had hoped to use this with Mason jars to greatly expand my available vacuum storage for crushable/bulk items, without paying the high price for the containers. But it doesn't actually work, even when you think it does.
<br />
<br />In more detail: at first I found it impossible to get a lid to stay sealed on the jar at all - air would fill the jar as soon as the pump stopped. I found that this was because I was using new lids; when I tightened the lids onto empty jars for a few days to "work in" the rubber I got better results. After that, if I removed the "jar sealer" device carefully after running the pump, the lid would stay firmly on the jar, it was "dimpled" down indicating a vacuum, and took a bit of effort to pry off.
<br />
<br />I remained a bit suspicious, so I decided to actually test how good the vacuum was in the jar. To do this, I vac sealed a jar, then put it in bucket of water upside down, popped off the lid so that water would fill it only the extent that air was absent, then popped the lid back. The results: only 20% of the jar was full of water, the rest was air that was left in there after the vacuum seal - that is it left 80% of the air in the jar.
<br />
<br />For comparison, I did the same test with a regular FoodSaver container. The result: the container was 67% full of water. (I think you're not supposed to immerse the lids on those, but hey! in the interests of science... ;)
<br />
<br />The bottom line: this attachment is less than one-third as effective in removing air from jars, as the base device is when used with purpose-made containers. Even though the Mason jar lid seems firmly sealed, MOST of the air that was in the jar, remains in the jar. The device is ineffective: don't buy it! | 1 | 739 days ago | FS Regular Sealer
Does what it is supposed to. But go to Yahoo FoodSaver Group for lots of hints on how to make it work as well as it can. | 5 | 739 days ago | It works...
It works exactly as advertised. I've only used it on Mason jars so far, but it makes a good tight vacuum seal.
<br />
<br />Not much else to say about such a simple gadget... | 5 | 739 days ago | Does not work well with small jars
I am not sure if this is specific to my machine but the regular mouth jar sealer does not seem to work well for smaller jars: there appears to be not enough vacuum as you release the button to keep the lid tightly sealed. | 2 | 739 days ago | doesnt work
followed instructions and very rare that it actually does as advertised... will stick to the canisters | 1 | 739 days ago |
