We bought the Shaker to refuel our boat from canisters can. The refueling from canisters can be a big mess at times yes, so we were looking for an alternative. We have you seen in the last Shaker! After they had a whole season in use, we can recommend this pump each, pumping of liquids from A to B or must pour. The open end simply slide into the receiving container and immerse the page with the Shaker in the container to be emptied, shake a little up and down and you're going to flow.
