I'm pretty new to this whole vaping thing , going on a month now. Anyways my local vape store set me up with an MVP 2 and an Aspire ET-S clearomizer. The setup is working great for me. Here's my issue I want something comparable in terms of controlling voltage and wattage but I want something smaller and more discreet to use outside of the house. I'm also thinking of getting the Aspire nautilus mini. So with that in mind, what would be recommended for something smaller that could hold the mini or the ET-S clearomizer? One more thing right now I've been running around 5.8 volts sometimes 7 on my MVP 2. Any suggestions would be great.
