So, I'm down here at VapeStock 3 in Florida and I managed to get my hands on a Zenesis 2 DX-650 for the very nice price of $110 (I couldn't swing extra for the tank without sacrificing gas money...sigh). These have the gold plated contacts and voltage drop is slim to none but I noticed the battery rattled a bit. We had a chance to chat with Zen and he's asked everyone who purchased one to get the word out...the battery is supposed to rattle. Apparently it prevents arcing which is a big contributor to dirty contacts. The bottom button pushes the battery up until it contacts the top post. To be honest...I don't even notice the rattle anymore and this thing works wonderfully. As for the VapeStock itself...not as big as VapeBash and far fewer vendors but it was still a good time. It got darn hot for awhile but things got better after the crowd thinned a little. I don't believe they expected such a large turnout. Still an awesome event and had fun chatting with lots of fellow vapors (seemed to be a larger number of new vapors at this meet so we spent a lot of time educating...very enjoyable). Sorry for the single paragraph post...my enter key isn't entererering.
