Title: Not worth it for the reason it's advertised.
Product review: Mine worked for a week and then it started losing the vacuum seal after about one minute after pumping shut off. Cleaned everything and still doesn't hold a seal. I like the canister size and it will keep coffee fresher if the vacuum seal pump is not used if it doesn't hold the seal because you will be inducing air into the coffee every time it pumps down. I took the batteries out and now I just use it as a regular coffee canister. Disappointed that it stop working right out of the box.
