Get the Buzzkill instead, has variable voltage, cheaper and better with easy battery change. Notcig.com, read up on it.
Just ordered one. I'm pretty excited about it - looks to be an excellent product. I'm a carto user so I'll have to wait about a month for my 901 to 808/901 adapters to get here but whatever, that is the most exciting Mod I've seen in a long time, since MadVape's Mini-Vapestack at 3.7 volts. It will use the same
batteries too so that will be nice. I can ditch my 3.0 volt
batteries now and just stick to the Ultrafire 16340/CR123s.
Thanks for the recommendation. Not a bad price at all for the technology in it. I figured the first thing to come out would be an 18650 set up with a switch to step up the voltage to 5 volts like the Fistpack, but more battery-change friendly. No more watching for someone to make that though, the Buzz will fit the bill just fine (I think/hope).
