This is a very delayed answer, and actually I don’t even know the answer, but I was in a similar situation of reading about the seaflare and wanting to try it but not being able to find one. Of course now, they have become readily and easily available and I have purchased both the pro (large size) and the standard. I haven’t tested it yet, but will soon be in Roatan and we’ll see how they workOutside of my swimming pool! The fit and finish, the box presentation, and the function so far is outstanding and I am just loving it. Hopefully, it proves to be worthy of its name when I test in in Roatan in August.
