Would not return $300 defective mod. This is a smoke shop trying be a apart of a community type product. Lifestyle products must have top customer service to have loyal customers. Which has been my feeling for a while. Testing out other places, Vapor Vortex, Vape Central, Valor Vapor and J Vapes is where you want to go. Have them one last shot and they blew it....sad they sold me my first vape pen, will never shop again at Liquid Vape again. I should have know, typical hagi smoke shop management just trying to take your money.
