I received my replacement VAMO today, and I'm ecstatic to report there's a huge difference between the two. So far I've tested on a Kanger T2 short wick, and the Kanger Protank 2 previously noted in this thread. There's been a significant improvement in how it handles to both tanks.
I was surprised to be able to move the Protank up to 7 watts on a 2 ohm coil and still get some solid results. Hypothetically I should be able to get to 8 and still be in the higher temperatures of the good flavor zone, but I didn't have the guts today.
Thanks to everyone for the help, I'd have probably still be pulling my hair out trying to figure out the problem.
Extra special shout outs to JeremyR and BaDaBooM.
Oh your so lucky I cant go above a 3.0 and its always burnt type taste no matter what I do, trust me I tried everything? I use a Protank on it? Any I ideas Its also the Vamo 5 in Stainlss steel and brand new
Not sure if you read this, but the OP returned his Vamo and the new works much better. Could be some bad ones out there, best of luck. Also did you try the RMS/Mean setting I mentioned on the first page?
