Thx's Shawn for your updates. I bought 15 LR from ya, (just so I dont run out) and got halve red and halve clear before you even had the color option available. I hate the red ones cause they look pink to me. Anyways I'll keep them not that big of deal to me. They also went though another revision it looks like. The center back up spacer under the seal that the mouthpiece sit on has an extended cone on it now. Reason for this is so you can not feed to much
juice in while filling that would over flow to the batt. BUT, this reduces the airflow since the ID had to reduce to accommodate this engineering change. I am drilling out this center to 3/32 to achieve the same type of airflow as the previous models. Not your issue, but thought I would share this here.
