I have many strategies that I use to help to teach the correct kicking technique, but sometimes they don't work. This device help make my students feel the bending of their knees. It was helpful.

None of the kids I work with are willing to use them.  Those that have tried can still bend at the knee.

This is a good product for helping skinny little kids flutter kick with straight legs.  However, if a kid is larger, it does not fit.  I wish Speedo would make these in small, medium, and large sizes.

Excellent tool for young swimmers.  Prevents the bicycle kick so you can begin to teach correct leg position

This really works to help young kids who struggle with poor kicking.  Although it is recommended for kids 2-10, it does not fit young kids with big legs.  I have had swimmers within the age stated that it just does not fit.
