Review on ☕ Coffeevac 1 lb: The Best Vacuum Sealed Coffee Container with Black Cap & Body - Premium Quality by Amy Mcleod

You can hear the suction when the lid closes, which makes me feel like it's blocking the freshness, but I've had it not long ago so can't confirm how long the freshness lasts. The only downside for me personally is that I find the design a bit awkward to maneuver as I can't hold onto anything on the canister. My old canister was a similar shape but also had a zip closure that I used to pull it out of the corner it was stored in. This clasp broke after a few years of use, so this time I purposefully searched without it (didn't know I'd miss it!). This canister does the job, just wish it had a handle on the top or side to use for agility issues but otherwise no complaints, it does what it advertises.
