Fantastic product. The results were immediate. Position of body in water and ability to move arms without restriction. My daughter still needs to use it to build on strength but she is now much more confident and having fun!
My son is confident in water but not yet able to swim. This has given him the push he needed and he is excited to be off on his own. I imagine the "shark" fun factor will continue long after he can swim unaided.
The Swimfin is possibly one of my best buys ever, I bought this for my 6 year old daughter who used it for half a day and could swim. I was amazed at how quickly she learned to swim and how her confidence grew. The swimfin is still being used to help her with her technique and I would strongly recommend this item to anyone with children who are learning to swim.
