I just broke the O-ring that the airflow adjustment moves on. Probably my fault monkeying with it. It does not come with spare O-rings.
I have purchased 3 green and 3 red cubis so far. Each one has a broken o-ring.
Same one you are talking about.
First one was bad out of the box, the rest broke within 2 - 3 weeks of use.
They seem to break when filling the tank.
If it had only been one I would agree to user error.
But 6 separate tanks.
I highly doubt it is user error.
My wife and daughter have each been through 3 each and they both vape differently.
I just can't imagine it being a careless act on their part that is causing this super thin o-ring to break.
I am NOT saying that it is impossible, just not likely.
The downside, after 3 messages, still no reply so I am not certain where to get the replacement O-rings.
Granted, I have not taken the time to measure or search very hard yet.
Then again, I should have to.
They should at least have replacement parts on their site.
If you happen to know a part number for this o-ring or where I can get them, they'd have more than juice carriers.
(At least they still work great for that)
