Presently considering a purchase of the Pro-vape 1. I am presently using Joye eGo-t and love the convenience of the tank system. ProVape is selling an adaptor that allows the use of eGo-t attys and tanks. This looks to me like a marriage made in heaven. Can anyone advise as to the value of purchasing the ProVape 1 besides the mechanical aspects. I am looking for the best and cheapest way to Vape.
