Fast forward from my initial visit.  This is the SECOND time that I have purchased a mod from this business and have it epic fail within 30 days.  I went in for a simple exchange because my mech mod had a short in it.  Most of the employees were just sitting around and had a blank, uninterested look on their face. They put copper dielectric grease on it and used a grinding wheel and said it was fixed.  I want a mod that works right out of the box.  I will not be going back for anything.  Substandard equipment that is priced almost twice of other outlets.  Pick n Puff MUCH better.
