Ive had my amod wotofo zna 30 clone now for about a month, and absolutely no issues. My one little thing is that mine does say mdoe , instead of mode. haha.BUT, its not like it affects performance. i use red efest v2's in it. have 2 of them. sometimes a battery will last a whole day with me vaping 20-30 hits per hour. overall, i love this thing so much more than my old mechanical.
Liking mine too. Don't care about the MDOE thing also. Just wish it had the ability to go to stealth mode quicker and easier.
