Well for the actual ecig, if your just starting start out with the ego twist or matchfree piece, they vape well and hold a lot of e juice so u don't have to refill as often As for flavors, I usually don't smoke ones with any nicotine, highest I go is usually 10mg because I don't like the taste of anything higher then that. Good flavors are the classic, unicorn milk, school lunchbox, and blueberry fizz (it's almost like a soda flavor) Hope I helped
Oh and in my experiences, the highest mg with the highest voltage might make the flavor taste burnt, so even it out carefully By tasting burnt, I mean it will taste like your smoking ashes it's horrible (you'll know when it's burnt)
