I think I may have a defective tornado. I ordered it from totally wicked on friday march 26th and received it on monday morning (very impressed with the speedy delivery!). I started vaping right out of the box. Plugged it into charger to top off (only took 30 minutes and it was fully charged again). Now it is friday night and I am still vaping on the same battery. I've even cleaned 3 attys with the 12 second dry burn 4-5 times each. I am starting to think that the battery will never die. I have the other one with me and ready to go but refuse to swap it out til this one stops vaping!!!!! PS Still producing tons of vapor !
