I hang on to this and drift in the pool to gently stretch my back.  I would slide off the plastic ones.  This is really solid and I think will last.

I will be using the ring buoy with the throwline I bought with it to rescue anyone too close to the docks that need to be pulled out of the current of the river.
It is a nice size to write our family name on it so that nobody takes it from my dockside.
I wish that I would have gotten a preprinted ring so that I didn't have to try to find the right size lettering to get all of the information to fit properly.
Overall,  I am happy that I get to personalize it the way I want, since it is really just going to be used in the event some needs help and I looks nice out on the dockside.
