-Small: can easily be carried on a canoe or paddle board
-Easy to maneuver
-Long solid rope with clips
-Comes in nice water proof bag
-Floating ball at the end of rope makes this impossible to lose
-I used it on a 300lbs canoe and it still was able to stop it without any issue.
-Great for fishing! My main use
-I bought myself something similar to this last year but I had to cut the rope. The way they are made the blades extending out makes this a easy target to get stuck under a rock or dead tree. In a canoe it it possible to pull on it really hard to retrieve it, but on a paddle board you are better off just cutting the rope and let it be (unless if the water is not deep and you are willing to got and get it).
-Weeds gets easily tangle around it. You constantly need to clean it when retrieving
