Hello I am new to vaping and changed the coil in my evod mega the guy at my local vape store that I bought it from sold me a 5 pack of coils when I first got it a week ago. I changed coil using directions it came with (simple and easy) after it started to taste burnt like he said and it made hardly any smoke and I got liquid in my mouth. After cleaning everything and reassembling it still floods out. The coil that came with it says 2.5 ohm on the side and has two small holes at the bottom and the replacement coils say 1.8 ohm on the side and has one big hole on the side. Did he sell me the wrong coils for this unit? Or am I doing something wrong.
