Except that the electronics are included in the vapor path. Other than that, the E is a good dual mode vape. If you're not really interested in bag use though, an analog whip model like the DBV is a better performer, hit wise, and more reliable long term, with no digital circuitry involved. The 7th Floor vapes also restrict the vapor path to just the heater cover as well.
