You will neep helpers to put you in the water and get you out again (the things are very heavy and you can move even less than in a "normal" tail).
Plus, they will easily cost double that of a tail on the market.
There is probably a reason why such tails aren't regularly made and sold, they are movie props.

You might be able to snag one which has been used and is sold after.
I know some mers here have attempted to make a similar tails themselves, but I haven't seen a ready to use version so far.
Thank you so much for your honest answer!
You are completely right and it must be quite difficult to use.
Do you happen to know a mer who makes them and sells it for private use?
