After using my VVN for a few weeks I've decided I don't like it. Sometimes the flavor is awesome, sometimes there's no flavor period. I'm getting nasty dry hits, using heads like crazy, it's started flooding pretty regularly. I hate how the post is to long and it sits sideways on my PV. So, I've ordered my 1st carto tank. Got it from Valley View Vapes. It's a 4ml Pyrex tank. I ordered the premium tank with aluminium caps. I also ordered a pack of pre punched and tested boge LR carts. He was out of stock of the SR so I'll pick some of those up later on. Hopefully this will be a good glass tank and I'll get plenty of good use out of it with good flavor and vapor.
