I started with V2cigs, then went to V4life, since they seemed about the same company. For the filled carts, I prefer V2cigs. However, I'm starting to venture into filling my own carts, since this is fairly simple and much cheaper.
For a starter kit, V2cigs is great. The customer service is good, and they ship very fast. I ordered some prefilled carts from them not too long ago, and there was a problem with one flavor. They not only got back to me fast, but also found the original flavor and shipped it within a very reasonable period.
I will still use V2cigs for prefilled carts, but found cheaper alternatives for liquid, as well as parts. If you want a whole kit, i.e., starting, they are great. But the further you get into vaping, the more you will go to less expensive, and more customizable parts.
