1/2 LB – Patented Airtight Container | Multi-use Vacuum Container Works as Smell Proof Containers for Ground Coffee and Coffee Bean Containers. Green Cap and Clear Body

I store both beans and ground coffee in these. They seem to do a great job. Easy to clean in dishwasher.

Love how fresh my coffee is in this coffee vac

Been using these for years great way to keep your coffee beans or grounds fresh

I've already got six Tightvacs and am buying four more today. They do a good job of slowing the staling rate for very fresh whole beans.Some of the people posting on this product do not understand what the term "vacuum seal" means in this context. It neither means nor implies that there is a perfect or near-perfect vacuum in the canister. Rather, if you try to raise the lid of a properly closed Tightvac without opening the valve, you increase the volume of the canister without allowing air to enter, that lowers the pressure in the canister (PV = NRT), making it impossible to remove the lid accidentally. Thus, no new air gets in unintentionally.In terms of slowing the aging/staling process, coffee stored in a Tightvac which would otherwise take five days to age and fifteen to stale, takes about ten to age and thirty to stale. In other words, a Tightvac works very slightly better than a can or heat-sealed bag with a one-way valve.The more completely filled the Tightvac, and the less frequently opened and closed, the better it works. I store my fresh roasts in the one pound size Tightvacs, use about half a canister to fill my grinder hoppers or for blending, then switch the remaining beans to a half pound size canister.They can be stored in the refrigerator or freezer as well as at room temperature. The combination of Tightvac and freezing stops staling dead for months.If you're using pre-ground coffee, the freshness battle is already lost. In that case, a Tightvac won't be any better than any other sealed storage -- a Mason jar for instance.But for anyone who wants to store freshly roasted whole beans, particularly for someone who roasts, these things are gold. And for someone who stores a lot of freshly roasted whole beans with the intention to post-roast blend, they're diamond encrusted platinum.

Simple, works, easy to clean, and perfect size. Holds my 10oz bags almost perfectly every time.

This is a nice bargain for the price point. It's well made from a thick plastic, operates easily with only one moving part, and cleans up easily with soapy water.A partial vacuum is created when you push the top down onto the canister and most of the air is expelled automatically as you depress a small button on the lid.This size easily holds 1/2 pound of coffee, ground or whole bean.The only reason thing I would change if I could is that the manufacturer should have had the foresight in the design stage to make these stackable, so you could have your sugar container (and whatever else you want to stack up on your shelf or counter) neatly stacked with your coffee. I mean they will stack but not snug into each other so they don't slide around or knock over too easily.I did pack this in a travel bag the other day for a weekend trip to the beach. Had no problem with it staying securely closed either.If that last point doesn't matter for you then it's a 5 star review!! BTW - I paid full price so you can know this is an unbiased review.

storage of coffee.

It keeps the coffee fresh and, most important for me -- not too large, just the right size for the kind of coffee I use.

Pot is good, concept is good and it appears to work well. It is more flimsy that I anticipated.But, beware the sticker on the lid. Whatever adhesive is used for the sticker, it is almost impossible to remove. The glue is appalling and leaves the lid very sticky and smeary. I'd advise leaving the sticker on, even if it is ugly as hell.

The container keeps the coffee beans fresh. The lid is easy to remove and replace (with a nice whooshing sound). Far better than leaving the beans in the bag, and they are much more accessible to the spoon. The 1/2 lb version takes 250 g of beans.

Container seems fine. As others said, the sticker is terrible and it doesn’t come off. Goo remover lifted the black colour off the plastic. Why would they put stickers on like this?!

Brilliant design does keep coffee fresh. Unfortunately it’s made of very cheap plastic, polystyrene, that is brittle and scratches easily. Mine cracked after about two weeks. For the price, I don’t see why the manufacturer wouldn’t have used a better plastic. Furthermore, polystyrene is not widely accepted for recycling, and can be toxic when heated.

Perfect for coffee beans!
