Started with $20 Smart (tm) ecig, it was a wretched device, went to an ego clearo and 1100 mAh battery, it sucked, got a 1300 spinner and a Kanger Protank, was happy for a while, then bought a mech, a Sigelei 24, which went through Protank coils fast, so I got good at rebuilding those, but got tired of that, then got an AGA-T2 for my mech, and finally I was happy... but I want a Magneto, and have a Sentinel on order.
