Query: Disappointed

While this set is not the most expensive, it certainly is not the cheapest either. And I expected quality workmanship from a product with quality (silicone) materials. I had the same problems with the snorkel that some others did but I could get used to it. It's kind of a trade-off for such a dry snorkel. But the biggest problem is that I bought two of these sets for a Caribbean vacation and one of the masks had a slow leak from the very beginning. We were on vacation for a month so no returning the darn thing. Now I'm here shopping for a replacement for an upcoming Florida Keys vacation. Not good.
