Worst customer service I've ever seen! Flat out fraudulent! First of all, I bought five items & three were defective! Not only did they demand videos to prove my claims, ( in 54 years I've never had a company do this to me! WTF?) then they only honored the warranty on one! Furthermore, one was a battery that was clearly 100% defective, and they told me they don't warranty batteries. It would have been nice had they told you that on their website! Even worse... The tops on BOTH falcon king tanks I bought were defective and wouldn't open right. The crazy part is that they approved the return on the first tank, but denied the return on the second tank, and the second tank was even WORSE then the first one! Now I know why they use a PO box and don't accept phone calls! Element Vape is the worst company I've ever dealt with! Going back to MVS.com!
