Don't worry if you have an issue with the Booster, all you have to do is contact Artisan Vaping and they will send you a new one.
The Booster comes with a six month warranty. The difference in dealing with Artisan (as opposed to products made in China) is that
they (the manufacturer) make the unit and stand behind it. Warranties for stuff made in China are usually a vendor warranty, since the manufacturer doesn't
replace defective units, its the vendor (in this case TW) who decides to stand behind the product.
Oh, and just FYI, the return rate for the Booster is about 3%, which I am told is similar to products from the JoyeTech factory. I've pulled the
connector out of the tube of an eGo battery many times, it really is a weakness in the design of the eGo, per se, not necessarily the Booster.
