I recently purchased a smoktech 510 atomizer. It works perfectly for trying eliquids I had made to see what changes needed to be made. Unfortunately they don't last long so I want to buy more. But they were the cheapest i could find any atomizers for and at 4 dollars its not exactly something I'm just going to run out and purchase 10 of without doing my research. I don't care if one has better taste quality or lasts a little longer i just want something dirt cheap that will vaporize my liquids. Also I already bought a 5 pack of cartomizer a for $5 and I've found cartomizers don't do the same job.
