1/2lb Sempre Fresco - Vacuum seals with a push of a button, Blue Rainbow

I like the look of these, but the lid is tough to remove and replace since it has to be perfectly aligned to go on and off (yes, I'm holding the button down). "Vacuum" is present when the pressure inside the container is lower than the pressure outside.the container. Tell me, how can that happen here? The answer is that it doesn't happen here. There is no vacuum in these containers. Yes, when you are actively lifting the lid, there is a slight vacuum inside, but as soon as you stop lifting, there is no vacuum. The lid seems well sealed, but this is equivalent to any lid on any jar. The name and tag line of this product suggest that these containers remove the air above your coffee to keep it fresh. That does not happen. Period. There's nothing wrong with these containers, but don't buy them if you are looking for vacuum packing.

"The Ultimate Vacuum Sealed Coffee Container". Blatantly false advertising. Creates NO vacuum. Air valve merely allows the air in the cap to escape when the cap is pushed on. Same volume of air in canister remains.Very thin plastic. Way over priced for a mediocre quality canister. Immediately returned.Note to manufacturer: It needs a small air valve in the cap that would create a vacuum if pressed repeatedly. So a proper valve and thicker plastic and you would have a good product.

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.

I don't know if this actually helps the beans last longer, but it it is well built. The two parts do seal well and require the button to be pressed to open. It doesn't create a vacuum inside until you pull it apart.If CO2 is pushing O2 out and if that improves the life of coffee that's good. I roast my own coffee so I rarely have beans beyond 3-4 days old anyway.Update 8/14/16 - This is pretty thin plastic and despite taking care while using it the lid cracked all the way through one side Other reviews mention the thin plastic and I dismissed them but it is made of a brittle thin material. I'll seek out a sturdier container. I'd expect a tougher product since it is made to be in daily use.

I love everything about this, including how easy it is to open and seal closed.The 1/2 LB size holds quite a bit of coffee and leaves room for my scoop. It doesn't take up a lot of my counter space and I can actually keep it right next to my mini coffee maker and still have room for other things.I'd been looking for something like this because I either grind my coffee or buy it with chicory and leave it out in small quantities to use each day. This keeps the coffee from absorbing fridge smells and it keeps the coffee fresh when I leave it out on the counter throughout the day. Great price and now I am thinking of buying more in different sizes to store other things. One other nice feature is that I don't have accidental spills - like today when I knocked the canister over.

I recently got back into grinding my own coffee beans and maintaining the work of a French press, and I have three other TightVac containers. This is an appropriate fit for a 12 oz bag of beans, but I find it best to store half the bag at a time and freeze the other. I believe the container fits just about the whole bag to its brim-- but the container maintains peak freshness for about two weeks, and it takes me about three and a half weeks to go through a bag of beans with daily use. Maintaining freshness is all about keeping smaller quantities. About the container itself: It's a sturdy plastic, vacuum seal at the press of an innovative valve button. Stands at a little over 5" tall and is 4" diameter. The opaque black color keeps light out completely to maintain freshness. These are worth investing in for food storage.

Straight out of the box I don't think the product is going to last very long. It's made of very thin plastic (which I would guess is why it can't be cleaned in the dishwasher), and with cap on and off, plastic rubbing against plastic will wear. I can't speak for it being airtight or keeping contents fresh, but I do wish I had purchased something a bit more rugged. My confidence of this product is low, but I will give it a go. It was purchased to keep a few days of freshly ground coffee in my RV for camping trips, so we'll see.

I can't say that I keep coffee in this for very long. I really only grind and store enough to keep for a week. But I will say that it seems to get the job done. I like my hazelnut coffee, and it seems to be just as good the first day it is ground through the end of the week.The only thing I have an issue with is not that the lid is hard to get off, but sometimes it is hard to put back on. If it is not exactly perfect it wont go on. Oh well, other then that, which I can fiddle with as the coffee is brewing, I find that I like the button on the top, it is a lot easier then some of the other ones I have seen where the button is on the top in the middle, I dislike that, so here it is on the side of the top, which makes it easier to push and open.

Perfect for coffee beans!

Producto Recomendado.Entre las opciones de contenedores para café son muy buenos (no los mejores), la válvula sólo limita el acceso del aire, pero no libera CO2. Conserva muy bien el café en grano por hasta 1 mes, café molido no lo dejo más de 12 hrs. Considerando que la válvula sólo limita el flujo de aire, es decir no extrae el mismo, hay que se cuidadoso al elegir el tamaño del mismo de acuerdo al consumo, porque los vacs grandes irán dejando cada vez más aire interior conforme se use el café.Lo malo es que son frágiles, el plástico difícilmente resiste una caída (en vacío) sobre piso firme, definitivamente no sobrevivirá si contiene café. Adicional, hay que tener cuidado con la tapa al cerrarlo dado que es muy preciso diámetro (para evitar el acceso del aire), pero al ser delgado y rígido el plástico se puede quebrar al aplicar poca fuerza.

Dafür das es viel zu lange gedauert hat, ist es dafür sehr ansehnlich und überaus perfekt eingestimmt. Den letzten dieser Marke musste man halbwegs zusammenzwingen ...

Excelente recipiente que mantiene el café fresco por más tiempo que otros convencionales; además a un precio muy razonable. Hice un segundo pedido por tres más.

Habe eine größere Dose in schwarz für die Kaffeebohnen. Insofern wußte ich um die Funktionsweise und Qualität. Kann es nur weiter empfehlen.
