Ok well, I have only been vaping for a little over a month. I purchased the blu cig for my first kit ever and is what I'm currently using right now. I am having problems with battery life "as I am vaping quite a bit" and it seems I have to charge my batteries every 20 minutes or so. I DON"T LIKE THIS ANYMORE! lol it's getting really frustrating having to recharge every 5 seconds. and the blu carts never last that long, I smoke 16 mg carts which is the high nic level in the blu carts, so I bought some 18 mg e liquid from Johnson Creek to refill my cartomizers. Which is making them a little better when I refill them myself, but still not "the best". The battery life still sucks though. But I have been doing some research. "a little better than I did the first time around obviously" but I am having a tough time deciding between the Joye 510, joye 510-t, or the DSE 801 penstyle. those models seem good to me. Not really looking for the bigger ones like the Ego, or Ego-t, just something that will last longer than this stupid blu I have. I kinda like the design of the Tank system myself, seems easier and less hassle, I'm not sure if the DSE 801 pen makes a tank system or not, but really looking for some advice. I don't have any experience with vaping except my blu cig and am not a happy camper at the moment, so please someone help a girl out! lol. I will be dripping my own juice into my models, so not looking for any prefilled cartomizers or cartridges. Thanks a lot for reading!
