Welcome , but there are lots of PV's available (personal vaporizers) Reo's , Provari's , all the different GG's ( golden greek ) , Saber touches , Silver Bulett , and the list goes on and on . I happen to have all of these , and they all have their good , and bad points . In my opinion , the GG , is a very well engineered , all mechanical P.V But then the Provari , is also very well made , and as a VV ( varible voltage )
device it has it's strong points as well ...... I guess it really depends on what is available to you in Germany . There are a lot of European Mods / PV's that are fairly common , in your part of the planet . Zenisis , Orion , Galileo, etc . So a very large selection . Good luck in finding one , or several , to suit your needs .
