This is a great post and obviously a very intelligent person. Oplholik hit the nail on the head. Instead of buying cartos and attys that will work on your PV you can get anything and set the PV to the atty/carto. Also if you do make the wise choice of going with a Variable Voltage devive you might as well get the best one available, The Buzz Pro, Infinity Pro, or the VVPV from notcig.com. They are the originators of VV in the ecig industry and are the one that set the standard that's compared to. But the 6 way protection built into each of their
devices was a feature that's always been there. Even before the standards went up the safty of the customer was a requirement with notcig pv's. Sorry, this is starting to sound like a commercial and I was just posting some facts.
