I am a total newbie, vaping for a month and I am in love with it. I've been researching to upgrade from my iTaste VV V3 but I am a little confused. It seems like every mod has good points and bad. Maybe some of this is user error, maybe some is manufacturing. Looking for some advice... I've narrowed my choices to the MVP v2. It seems to have overall good reviews with the only drawback being that the batteries aren't replaceable. My other option is the Vamo V5, but threading issues on other Vamo's have me concerned. Any advice would be welcome. I only have so much money for this and I want to spend it wisely. Thanks.
