Was really hoping this would work for my intentions. I wanted to spot feed reef roids. Made a thick paste of it sucked it up and just like the baster type feeders it immediately started leaving the feeder as soon as it hit the water I really was going it would stay in the feeder until I released it. It didn't happen. Since I have a beater with the same issue, in returning it. It also can broken at the to like other purchasers but would have kept it if it worked.
