hmmm
no on the
C8 leaking ...last night I carried one (V3)in my purse (laid down in a case) for back up & it was fine when my CE5 finally ran out of juice & I was ready for it .
Kinda amazed me I really expected it to leak for some reason
I have had NO LEAKING from my version 1 or 3 since I moved coil over on #1 ...
you have checked (I assume) that your little silicone cap dude is securely pushed down in it's holes etc...???
The only time I have seen juice in the top is @ the end of filling when it starts to bubble out of 2nd hole ???
I have been filling these on their sides, keeping 2nd hole on top for the air to equalize as I fill.
Not as messy as the upside down fill & straight up fill,both of which just bubbles out a lot more juice.
WindLvr , be aware that the Blueberry might melt your mouth piece on the CE5 !!, been there done that ....
& be aware that the rocket 2 piece design allows juice to get in to the body ...so watch for leaks on carto's that you run on it .
Sealing the side seams & around connector @ the top b-4 using ...will avoid this issue .
I am only mentioning these issues since you are NEW to alpha & may have NOT read entire thread,which I suggest that everyone NEW should read back , cuz it might/should/WILL save you some anguish in the end
