Here's the bottom line regarding clones authentic clearomizers. I think people are a little overly scared about clones in general. If it works great, is cheaper than the authentic, and is regularly available then why be scared of it. I have used many clones and have found that with the right research you can find exactly what you need at a great price. Almost all of my tanks are clones because the truth is there are so many manufacturers in china that are making these things that over time most actually start making these better than the authentic company. I'm not saying every clone out there is up to par but if you find a supplier that has a good reputation then order a few tanks and see how they are. What i usually do when a new product comes out is buy one authentic and use it so i know how the tank is supose to feel like. then i shop around and find a clone that will match the grade of performance as the authentic version.
