Ok so I dunno whats up with vapexhale , who knows it may even be my bamboo but I am giving up and just not going to email them again bc it has gotten out of hand imo. I purchased some elbs during the sale , a 4pack for $20 , not sure if that was a sale or not but they all came to me and fit way to loose in my Evo to the point that every time I'd inhale they would fly up from the air pressure. I tried pinching them , stretching them out with no success so I emailed support telling them I know I paid for 4 but I only really need two tight fitting working elbs and if they could check them before shipping and they had agreed , I was able to keep my original order and two were being sent free. Those two elbs arrived the same as the others so I email support again and they have apologized saying it was so busy that they did not check them and would personally go check them and send me two more out which I feel was really cool that the customer service was easy to deal with and quick to reply. I get my mail yesterday , open the box and there is about 5 or 6 more elbs , guess what they don't fit 1 is super loose and the rest are so tight that I have to force them in and really be careful taking them out , they get almost stuck in my bamboo , one already smells of avb right out of the box. I just don't want to deal with support again so I am giving up. They tried and I tried. I am just happy it was not a expensive purchase and my next order for vapexhale supplies will most likely be through another supplier. I have my original 2 elbs that work fine and I cleaned them up and I can use the really loose elbs , just not inverted and they don't work as well as a tight elb but they work with the whip kit.
we're on opposite sides of the spectrum! 
experience wise, and you're definitely giving advice on your end! Thanks man, I wanted the full view on the standard mouthpiece and I understand now from what you said.
It's good you threw them out.
