I don't think of my Prodigy as a "Mod." A Mod is an unmanufactured homebrew that other Modders can copy and/or adapt in their own workshop.
The Prodigy (and other manufactured "high-voltage fat boys," as I call them) is one of the various types of e-cigarette, like the penstyle, mini, supermini, etc. It *is* a hybrid device (Chinese atomizer and cart + American battery pack).
BTW, I still use and enjoy my 801 (i.e., 801 atty + 801 battery), especially for my non-nicotine pacifier vaping, when I don't need (or want) throat hit.
If you have $140 available, the Prodigy (or GG, etc. if you prefer) is a great long-term investment (with short-term high satisfaction, while you're waiting for that investment to pay for itself).
Happy vaping!
