Alright guys, quick update.
Angelo has been superb in helping me out. The e-ciggs themselves are great. My batteries are lasting me over 6 hours with heavy vaping.
The carts hold an awesome amount of juice - however - like all magnum carts you run into the problem of the top of the poly fill drying out before the bottom, so you need to redrip anyway.
If you want a faster reply from Angelo - go into your account and look under Order History, post a comment to whichever order you are inquiring about. They take care of customer's as a priority - and their e-mail box is flooded with questions from non-customers. Using this option on their webpage, you are telling them you're already a customer.
Unfortunately my multimeter died literally while I was testing the atomizer, but I believe they're 2.9 OHM.
Everything about this feels like it's better quality, the wicks are slightly larger and a lot more sturdy than other e-ciggs I've used.
I have not had to do a return yet - obviously - but I would encourage everyone to be patient. With retail warranty's like this, you likely need to return the item - then they return the item to their distributor and send out your replacement when it arrives. That's likely a month+ turn around.
Angelo is a really good guy in my book - if you call the company and press 0 it will connect you directly to him, it's just a matter of getting ahold of him when he's not busy.
So far I am extremely satisfied with everything. This is my own personal experience with them. I would recommend buying two extra atomizers and 2 extra batteries, just so you can wait for the warranty turn around.
Like I said, for a faster response - use your order history option under the account on their webpage, rather than e-mailing them.
I'll keep updating my results with these as they get more use, but so far they're flawless. Produce heavy vapor, battery life is very long for a 510.
