Pluses: easily adjustable. Seem sturdy.
Minuses: My foot slips off when pushing during forward stroke. No grip and seen from above, the braces taper, getting narrower toward the center of the boat. My kayak is 23" wide at the cockpit/21" wide at the braces.
Keepers were flimsy, but my foot didn't slip as much as they did w/these Sea Dogs. Bummer.
