I have both. The Prodigy vapes at a higher voltage than the pt if you are using the 5v version becuase it runs closer to 6 volts, where the pt runs closer to 5v or below.
I get a little less vapor and
throat hit when comparing fresh
batteries in the Prodigy to the pt.
If you are comparing to a 3.7v Prodigy, then you will probably get an increase in vapor/
throat hit using the pt.
I don't use the pt, I have it as a back up only in case of Prodigy failure.
