love this canister. And as you’ll see further down, I’ve come to love the company, whose customer service is astounding.I first heard of the Atmos when I saw it praised on YouTube by a marvelously thorough British coffee expert, James Hoffman. Who did wonder about paying $30 for a storage canister, but found it kept coffee fresher than any other option.I say that if you care about coffee — and maybe spent at least this much on a scale, and much more for a grinder — there’s no reason you wouldn’t want the Atmos. Which, on top of how well it works, is elegant, and a pleasure to use. After you close it, you twist the cap back and forth, until a button on top goes down, showing green from the space around it. This expels air from the inside, so your coffee sits in something approaching a vacuum.Then, when you want some coffee, you press a button on top, and air whooshes in. Now you can unscrew the top. And smell fresh coffee.Of course it won’t keep coffee fresh forever — nothing will — but it does a great job, And gives you confidence that it does, because it’s both elegant and solidly built, and because you feel the air going out as you twist (the twists keep feeling firmer), and because you can hear the air whooshing out.So, customer service! So many points for Fellow. When I bought this, it didn’t work. The seal wouldn’t stay sealed, for more than a few hours. When I told them about this, they replied the next day — on a weekend (!) — explaining what the problem was, and suggesting a fix.And then on their own initiative, they emailed two days later to ask if the fix had worked! It hadn’t, so they immediately sent me a new top for the thing , even sending email updates, as few smaller companies do, tracking the shipment and telling me when the item would arrive.The new top works. Happy customer.One note to anyone buying this, and a suggestion to the company. Expelling air from the thing can take as many as 30 twists. Nothing that comes in the box tells us that, so at first I thought the seal didn’t work at all. Maybe Fellow doesn’t want to scare us off, but still, since this is a fact about the canister (as they confirmed to me), we might as well be told. If anyone thinks 30 twists is too much for fresh coffee, that’s your choice. But I’m not bothered. I could even say I’m helping out with my coffee’s freshness, and getting a little morning exercise. ?Highly recommended, especially for coffee obsessive. I also btw have Fellow’s Ode coffee grinder, a truly thoroughbred piece of gear.
