I have been using my Magic5 goggles for over two years now. In that time I have swam over a million yards using them. I have been swimming for five years now and while not a long time, I had previously owned multiple other pairs of goggles, both well known name brands and not so well known, but the Magic5 have out lasted and out performed all others. I have been very happy with the durability and functionality of these goggles. Just today after over two years of use the flexible material around the edge that helps form the seal tore. I’ll be replacing these with another pair of Magic5 goggles.
