Good, simple, and cheap buoy. It does the job. The little flag fastens very well, it washes easily, and dries quickly. Unfortunately, though, as others mention in the comments, due to its construction and shape the buoy very easily tilts downward, with the result that the little flag often touches the sea. Personally, because I want to be equipped, I carry things on it (tied underneath), so it keeps it upright, but generally if you want it simply to protect you from boats, you may need some counterweight underneath or another shape to buy. !!Definitely!! buy a reel; the rope drove me crazy, it kept tangling all the time and was very thin, so I constantly had to untangle it. You can replace it if you want with a better one, but with a reel it works perfectly and the tangling issue is solved. It inflates in no time and I didn’t have any other issues. I will definitely keep it for now, but later I may upgrade to a better one that will also offer me more space with clips, straps, and pockets. I recommend it for a simple trip to the sea, but only up to that point. It has also helped me at times when I wanted a little rest and just held on or floated a little on it.
