I currently vape all day long on a kangertech mini. It's good for all day use. I have been looking into getting a bigger (150 to 200 watt)unit for casual drip and maybe a little showing off at the local vape club. So far I have looked at the snow wolf, seiglei, tesla, ect. I am looking for suggestions and at least a vague hint as to why you prefer your suggestion to some other units out there.
