Hey just copped a Aspite Clieto Tank a couple of weeks ago and everything was working fine with the original coils, great flavour and airflow and blowing some decent clouds but after those got burnt out and i copped the 0.4 replacement coils i get a spitback issue where i get e-juice in my mouth after every hit. And im supposed to be able to run them at 40-60W, but for some reason i cant run them past 38W (under 4.0V), gotta run them it at 30-35W (then i get 3.76V) but the vapor production is weak and i get alot of e-juice in my mouth on every hit... Kind of sucks since this was one of my favortie tanks, anybody know what the problem might be or had the same issue? Kind of a noob when it comes to this vaping shyt only been vaping for 2 months or so... Would appriciate some feedback
