Looks reasonable as a support when your child is being taught how to swim (and is thus closely monitored). Looks absolutely horrible as a means of preventing your kid from drowning though.

disclaimer: I'm not in any way a professional when it comes to water safety, so this is just a remark; not advice.

Yea, it looks like a useful tool to provide support while following the warnings:

Warning: Not suitable for children under 36 months Warning: Only to be used in water in which the child is within its depth and under adult supervision Warning: To be used under the direct supervision of an adult

I don't think it's a mistake that "under adult supervision" is said twice.

I'd definitely not let him out of my reach, he's far too young.
