Good deal, you're back in business. Nothing wrong with a C-Twist. I used to own several before I sold them in the classifieds. A slightly better piece of gear-- I found the twists annoying because the voltage ring would turn while I had it in my pocket and I was forever checking it-- would be the innokin VV4 battery. It's the same size, roughly, as an eGo battery, offers both variable voltage and variable wattage (3-6v, 6-15w), 1000mAh, both eGo and 510 threaded, charges by mini-USB and is vape while charge. It preserves the pen-shape image and is not a complex piece of gear. You can find them online in the $30-40 range.
