I’ve been using the fury edge for about 2 months now and can happily say, it has exceeded my expectations in a portable vap! I’ve been using a “desk top” plug in style vap for well over 10 years and never expected this little unit to become my fav! It’s incredibly efficient and has proven even more economical than desk top, which speaks volumes for its value as my desk top is a very efficient unit. Huge clouds and fantastic flavor in a very economical, discreet package. Plus, the comfort/luxury of truly excellent customer service. Buy one, you’ll be echoing my review in short order!😎
