Yep, I bought from Innovapor and his stuff works great. My order got here fast. Has lots of different kits to choose from. Great communication.
I have a pensytle ordered from ruyan direct but I haven't received it yet. So I can't say anything about them. But I have read good things about them.
I want to get and try one of those inline usb batteries for my 510 or penstyle. They hook up to the computer so you can vape, and not use up your regular batteries.
From what I read, don't go with Blu. Cross that off your list.
I hunt around for the best deal I can find too. I can't afford a lot. I guess you have to figure out on how much you smoke now, and the price per month. Then figure how much the e cigs cost price per month. This is healthier than smoking.
Which ever one you choose, make sure you have at least, 2 batteries and 2 atomizers. Maybe 3 batteries. I have one charging, while I use the other. Get some trial sizes of juice before you buy something big you don't like.
I will tell you one thing, shipping prices is what scares me off from some places. I don't order lots of items, so when I order and the shipping is more, or as much as what I'm ordering, it scares me away. I look for discount codes, and free shipping a lot.
