I just recently got into vaping. I'm so glad, because I was a regular cigarette smoker, and now I'm leaving that behind. I've instantly stopped smoking regular "analog" cigarettes. I've switched to vaping, and I'm not going back.
I bought one of these kits that includes two Ego Twist 1300 mAH batteries and two Iclear 16 clearomizers and the charger:
I got one red battery and one blue battery, and one clear clearomizer and one blue-colored clearomizer. One of these adjustable-voltage 1300 mAH batteries easily lasts all day, even on high voltage; and the other one serves as a fully-charged backup. The kit with two complete units was $79.99. They can probably be found cheaper somewhere else, but I don't care, because this excellent kit is what got me off regular cigarettes, so it's very cheap in the long run. Just one battery lasts all day long, and the voltage can be turned up higher than I want it to provide an extremely powerful vape, and it still lasts all day long.
My local shop is here:
My all-day vape is:
(It was called Abbey Road, but they must have got a copyright notice, because they changed it to "Abbey Lane."
My other favorite is:
That one is butterscotch flavored.
There are a million shops now, so if you aren't getting the customer service you deserve, you should switch shops. Everybody's mixing flavors now, so they are virtually unlimited.
