Got this today, straight outta the box been having low res issues. Tried with two tanks and several coils, no fix, or sometimes it will work for one or two hits then go back to low res. Also doesnt read resistance accurately and temperature control seemingly doesnt work, it doesnt noticably fire and resistance goes up from like .7 to 2.8 or something like that. Also get high res as well that doesnt let me vape. Considering returning it very disappointed.
