I am writing to thank you for the snorkel mask I bought from you last month. For the last 5 years, I have vacationed in the Caribbean, where all of my companions enjoyed snorkeling but because of my poor vision, I did not. This year, I could actually SEE the fish! It was a whole different experience. My new "Sea Rex" mask fit well, and the prescription lenses were perfect. I also appreciated your extra-fast shipping. I am passing your catalog on to friends who I think will be interested in ordering their own snorkel masks.
