Review on Airscape Coffee and Food Storage Canister: Innovative Airtight Lid Maintains Food Freshness | Stainless Steel Container, Small Size 4-Inch Canister with Two Way Valve | Brushed Steel by Jill Graham

Not bad overall. Some reviews say this keeps your freshly ground coffee fresh - that's not true. My freshly ground coffee has clearly lost its aroma after a day in the container. But if you look at this product as a whole, I would say that it adds some oxygen protection and offers a lot of convenience when making coffee (compared to storing ground coffee in the original packaging). So if you're rating this product purely as a coffee storage container then it compares pretty well to other methods I've used over the years. Pros: Easy to open and close. Enables quick coffee preparation. I think it offers some protection from coffee oxidation. Cons: If you push the lid all the way down, the coffee will stick to the bottom as you pull it out, making a mess. when you install it on the counter.
