They did send me out a new iQ but more so then just fixing replacing unit they kept in the loop and explained what should of happened what went wrong then came back to me sometime later to show how they had dealt with it going forward, I was very impressed esp with the representative on this...
It’s not exactly the same unit this model has Improvments over the last two units I bought, though they were bought one in 2016 and one earlier this year.
You see what I was saying about the cs not dropping and also the iQ is my favourite vape to put through a bubbler or glass piece, please check out my YouTube to see the videos and glad to help out
I do 10 mins at 380 and then 5/10 at 430 to finish off and I get around 5/6 sessions with the included 18650 my fogstar cell’s are a little better but I always have charged batteries
Give the DaVinci rep here a chance they were awesome with me, if I take both sets of gaskets and hold them up to the light your i the difference right away I also had the same issue lol
