Tactical Keychains review for SC Product Options

I just purchased the app, paid the $40 fee to have it installed. The app must be very popular because it said 3 day lead time. So I went and installed it myself - or tried. It is pretty complicated but the instructions are fairly clear. I'm using Vantage Theme, I'll edit this (hopefully) once I get rolling. From what everyone has told me, this is the go-to app for variations.
