Hey thanks for all the input. I think I am going to forgo the purchase of the swimmer's snorkel. those of you that recommended it,my hat goes off to you. I am basically a lazy person and really fear that I will use one of these as a cruthch and that I will have a hard time giving it up.
Like I said, I do notice some improvement in my breathing and swimming, but it seems that I have a very LONG way to go to even swim like some of you who have posted your videos. I guess I had hoped for a "magic bullet"!
Thanks again for all the input
