I've used above deck mounts for years. Recessing the rod holder mounts and making them flush with the deck is one of the best moves I've made. Where the former holders were always catching debris and getting in the way when paddling, these serve exactly the same purpose and eliminate all of those problems. My only complaint, if it can be called that, is that on some kayak models a slightly narrower mount body would have made it easier to install. However, that's more a fault of the kayak design than the mount itself.
