I ordered the 6v kit, but was disappointed for a couple reasons, all my fault. First I forgot to specify that I wanted the 5 Boge cartos instead of the atty. I had also ordered some Deluxe Fluxomizers at 3.5 ohms, but they were just burning the juice way too hot. I only had two SR Boge carto's to go along with the atty that actually worked. Not too great, but like I said, entirely my fault.
However, I just received the 17670 battery and charger along with some 2.6 ohm fluxo's and am in heaven. I think 6v might be too much for me but it'll be cool to switch back and forth whenever I want.
As for the Prodigy itself, I love it! It's a piece of art, and I super baby it. I got the Media Blasted and I really like it. The only thing I was kinda disappointed about with the kit itself was that it didn't come with Noalox but I just went to Home Depot and picked some up. Works great...
