Re: Do NOT buy Nammor.
I have (2) 1st run Nammors... I love them, hands down! I'll never replace them unless they break... I like my Razan, but like a few others - the red grommet came out and now I have to glue the sucker back so the mouthtip stays put. But.... I wouldn't trade it for the world.
I have heard if you drop the mouthtip piece, it can break, but I often hold mine (in my mouth while video gaming) by the tip and other than a few teeth marks, all 3 of them are peachy.
Now, don't get me wrong - I like me some MYA hoses too, but I have to have my Nam/Raz. One day I'll get a KM to see how they are too.... someday, over the rainbow...
