You had no idea the flavor was that good ? Well when nearly every review you read says it's unbeatable for flavor somethings up , glad you found out , if i was starting out i would buy it first instead of buying a ton of others that pale in comparison.
Now onto the build , i use a single large diameter coil (1/8th size mandrel) and like higher than normal ohm , anywhere from 1.2 ohm's up to 2.0 (yes 2.0) , this thing kicks out incredible flavor regardless of ohm range imo.
I like the larger size coil because it allows a lot of wick to be pulled through it , i leave the ends long and tuck both ends deep down into the well , fill and your in vape heaven .
Very important to make sure both air holes are open , you can easily leave one open and the other closed so take a look and make sure both are open.
Enjoy
