I prefer the Sweeny over most feeders. I run a pond management company but I do not sell feeders. I prefer to make a living as a consultant not a salesman. I have heard good things about the Stren feeders as well, but I have seen coons (or some kind of scavaging animal) tear away the wires on the Stren trying to get in. The Sweeny feeder is all incased with no exposed parts or wires. It is for that reason I prefer the Sweeny.
