Hello, im looking into some of the pen style vaporizers so I would appreciate your opinions ! I like the dube pen because its cheap, portable, inconspicuous & it seems to work from what iv heard. What im wondering is if their is a similar style vap that tops the dube ? Iv heard of the G pen but I think that's mainly for oils, can anyone verify that for me ? Also I was lookin at the AtmosRx, a little expensive for my tastes but if its really worth it I will get it. Thanks for your time & feel free to list any other models you know of I want a good product that will last awhile & isn't a hassle to use.
