Congratulations, Bill! It's always a happy day when what we order works well right off the bat!
Although I usually use a small softbox modified hotshoe flash on a bracket for my macro work, there are times and places that a ring light will be the right tool. I just purchased a Yongnuo ring flash for just a bit over $100 USD. It works great with my 100mm Canon Macro lens. I like the fact that I can regulate the brightness of the ring left and right to where I want it. It would be pretty under powered for anything but up-close photography but, it is great for that.
BTW: There are some fairly good YouTube videos on the TT685 and other of the Godox flashes. They generally give these units pretty high reviews...
