We recently bought a pair of 12' sit on top kayaks. They are great in the water, but can be heavy and hard to handle out of the water. This dolly is amazing. Super easy to assemble. Seems to be sturdy construction of quality aluminum. To use, you just pop the pegs through the supper holes, roll the kayak onto the wheels, and you are ready to go! Makes it so much easier to move them around, especially when you don't have a second set of hands. Update: The foam padding has come off one of the pegs, but it still functions fine. I don't think it's going to do any harm without that padding, so I haven't even done anything to replace it.
