Qcaj,
Firstly I want to say in my experience is that Canvape's low prices are only surpassed by their customer service! Whether it be just answering your newbie questions or doing what they can to make it right, just speak with them and they will do what they can to make things right. I am sure you will find if they can make it right in some way they will. I am so sure of this I had said to someone else if canvape shockingly didn't replace it I would out of my own pocket
Just contact them they don't bite unless you ask them too
My person experience with the
firebird wasn't all that good, I got too many dry hits. This was supposed to go away once it was broken in but I just gave up on it. When it would gurgle, I found you had to empty it and refill it once you cleaned it up. The filling procedure needs to be done upside down if memory serves me correctly.
Starduts: I had alot of the cracking in SD v1, v2 v2.13,v2.124, v pretend 3, v oh no wait 2.5, oh no not a real 2.5 but 3 that is really a 1.5 ( aka a lot of different ones with weird versions that apparently was not what it might not kinds sorta be ). This was happening due to the heat for me and not the juice.
I have 4 of the real V3's ( the ones Canvape have ) and have been using them for about a month or so now. I bought replacement heads and swap them out around a week or so, depending on their performance.
Every so often during the day I will unscrew the mouth piece and blow it out, because if I don't I will get some build up of juice in it, partially from juice unvapouring ( thats right its a new word I just made up but you understand ) from my power puffing, and small amount of juice eventually getting in there.
I have a vivi nova too, and because I am lazy I just use the replacement heads from the stardusts on it and the spike just pokes through the top. Replacement heads are easy to change on all of them and is cheaper than a new stardust
Sometimes you might just need to tighten down the replacement head, other times look at the bottom post to make sure it would make contact with your battery.
Good luck!
