Okay I'm confused. There is a tiny slit at the top of the orange silicone "vacuum seal" piece on top. How is this air tight? What am I missing????

Yeah, if you hold the lid up to the light you will see a little hole. However, among my numerous coffee storage containers and devices this is the one that always gives off that wonderful roasted bean smell when you open it, even if it is almost empty. My pump vacuum storage units and the silicone ring-seal canisters don't do this.]

If you're looking for what substance most quickly reduces the freshness of coffee, oxygen is the guilty party. A one-way valve prevents more oxygen from coming into the container, while also allowing freshly roasted beans to "off-gas" carbon dioxide (a natural process). You can't get rid of the oxygen that's already in there, so it's best to minimize the number of times you open and close the container.Here's a more technical description:http://coffeetime.wikidot.com/one-way-valves-and-coffee-storage

The "slit" is actually a one way valve to keep air and moisture out, but allow carbon dioxide to escape. I've used mine for many months now and have been very satisfied with the freshness of the coffee each day.

it seems to be the reason the coffee always has a good aroma and stays fresh. the slits allow the air (OXYGEN)to enter the canister at a slow pace. this allows the airmout and the carbon dioxide out.

There is a silicone valve, in the upper reservoir, designed to keep water in when no pressure is applied. That valve has a slit that may not have been fully opened during manufacturing. It is a simple fix. Take the valve out (something you'll do from time to time for cleaning anyway) and pinch it to make the slit open. Once you've done so, re-insert the valve and you should be good to go.

I too own an old Foodsaver vac. I had to cut the gasket in order for it to fit. It seems to work just fine for sealing but I haven't extracted air since buying it.

I tried it on a bag of M&Ms and it sealed it but didn't vacuum seal it. It made the noise like it was trying to suck the air out but didn't.

It seems to seal tight on the one I got but it has it's own casing that u can remove and place in its own compartment inside the container ... Hope this helps :)

It sounds like you may be missing the seal. It's a little round white/clearish piece that is between the lid and and the tip up piece.

We have a Food Saver vacuum with the attachment that seals canning jars. I just dumped a bunch into some quart-sized jars, shook the chives down until I couldn't get anymore in, and vacuum-sealed them. Word of warning though, pry the top off VERY slowly and carefully when you want to use them or they will fly everywhere when the lid pops off!

I have a number of these in different sizes. The ones I have are absolutely air tight. The ridges of the molded silicon gasket surrounding the top of the jar provide the flexibility to form a seal with the inner rim of the lid. There should be no need to add anything.

I just filled two of mine up today. I opened them slowly because the seal is so tight not even gas vapor can escape. There was a loud hissing sound when opened as the gasoline vapors escaped. that's how good the seal is. It locks down tight and nothing is getting out.

When saving items like soup, stew, ground meats, I dry the inside of the bag before starting the sealing process. I listen to the sound of the vacuum pump and watch as fluids get close to the sealing strip, then I press the "seal" button instead of waiting for the automatic stop. I get a great seal that freezes nicely. Hope this helps.

I tied ours off tight to prevent air leakage. I assumed it was for deflating the whole thing when you roll it up for storage.

Mine did the same thing. I just squeezed the air out and used a clip to close it. It's frustrating though, you spend so much money on a product, you expect it to have proper packaging.

My first question to you is, "Did you pull the black piece of tape off the sealing strip?" Hopefully, you did not. If you did, that's causing your bag to stick. Next, what bag are you using, VacMaster,FoodSaver......? If you pulled off the tape from the sealing strip you need to contact VacMaster for help.

I'm sure that has worked for you but I have not personally ever sealed off everything "air tight." It seems to work fine just like it is. Good Luck Marko

You can do one of 2 things. Hit Manual Seal (with the bag in the vacuum area) and it will suck for a second or so then seal. Or you can hit the start button and then hit the manual seal to stop the vacuum process. Hope this works, I surely like mine.

There is a stop button, but to be honest, with previous vacuum sealers (I have not tried with this one) my luck with finding that perfect point between nearly sealed and very squished is tough. YMMV.

The bags have a Ziploc type top. You then vacuum out the air. It works great for me, but I have had one bag that would not vacuum seal. Probably a tiny hole in it some where. Figured it was a factory defect which will happen.
