Product pretty much as described. It doesn't "vacuum" seal until you try to pull the cap off (creating suction), but it does do a great job. It would be nice to see an actual vacuum design soon.
Used this vacuum sealing container to transport some special herbs every now and then. When its in the engine bay, it really blends in with the engine and its accessories. Very tough and very air tight. I highly recommend this product and would buy it again if I needed another.
It is the perfect size for keeping my legs sausage spice in. Its bigger than a normal spice container but not to big. The vacuum seal is very nice and you can't smell the spice once the air has dispersed through the container. I'm very pleased I will definitely be order more of these in the larger sizes for flour and rice.
My only suggestion to the company would be to provide square ones instead of round. Square containers are more space efficient.... space is wasted when you use round containers and when you have a small kitchen like i do that becomes very important.
