First off, I started selling electronic cigarettes with custom cartridges. When I found a demand I went to ali baba to get the e-cig kits for cheap. It was easy to find a supplier, but for sure the lady I am dealing with isn't the factory, but she has been good. Few qualms though.
For one, she didn't want to use the ali baba payment setup. So the first payment was a leap of faith. On my second order (for about the same amount of $) she sent me different kits than the first time because one e-cig was longer than the other. I didnt know I was getting a modified kit until I received about 500 of them.
My overall experience with this random company I met through ali baba has been a good one. Each time they have lowered my price and even dealt with the dead units I receive (Over 100 dead chargers thus far... I have been taking them apart and resoldering them myself, but they replace each one). Would be nice to talk to the factory directly, but the people on ali baba really helped me launch a company through an IM window.
