" I just wanted to let you know that I have now tried both the Aquasphere seal mask and the barracuda ultimate goggles for swimming and for Aqua gym and they are both fantastic! I was worried that the mask might feel a bit big but that is not the case at all and it is very comfortable and because you have such wide vision with it you don't really notice that you're wearing it like goggles. Anyway thank you very much for your recommendation and I am now reading your book. Once again, thank you" Rebecca
