My 4 year old has this in pink & has become so water confident she's like a different child! I love that it gives her the freedom to still use her arms with no bulky bands in the way & gives her that little extra buoyancy to keep her head above water.
We adults used it and we loved it but It is not enough to my 6 years. He likes better the normal swim ring. I am happy and hopefully he will use it next years when he want to learn swim.
