Hey everybody I'm a new user to e-cigs, and I bought the blu cig which gave a good throat hit but it wasn't consistent. After a couple hits it wouldn't give me anything, so I ordered the Joye 510 a manual to make sure it would give me as much time needed to take a hit. When I take a hit from the Joye 510 I get no throat hit at all with the prefilled carts they give you in a starter pack. It's buggin the hell out of me so I tried the blu cig atty on the 510 and a blu cig prefilled cart and started getting some pretty good hits. For the life of me I can't figure out what I'm doing wrong with the Joye 510 carts and it has to be user error or a bad atty or am I missing something? I'm looking for an e-cig that gives a good throat hit and lots of vapor, but nothing big and bulky as I want to use it on the go for work an so forth. Any help is much appreciated and thanks in advance to any users that could lend a hand.
