Coffeevac 1 lb - The Ultimate Vacuum Sealed Coffee Container, Black w/Logo

Q: is it really air tight? if i store chopped garlic will the smell escape?? the real test...

Yes, very air tight and stinky food smells do not come out at all. I was so amazed as I really thought people were exaggerating. I have used it for dried fish... Yes fish and you know how toxic that is and not a peep of smell comes out the second you put the cap on. When you put the cap on you can hear the seal sucking out the air. Works for years. I open and close mine multiple times a week since 2014 and still works perfectly. I got the pound size. Buying a smaller one today will review how good the seal is on 2016 product when I get it.

Q: How easy is this to open/close? Does it take both hands to operate?

It is easy to open/close. It does not require strength. Closing is more like a push-down while holding a button on the side.I use one hand to hold the canister and the other to open the lid. However, you could use your arm to hold the canister if need be.It is a great purchase.
