How to use JY670 macro ring flash?

I bought this and the test was satisfactory. After all, it is a double tube, and the left and right output and light ratio are adjustable. It is not a problem to use it in digital SLR without TTL control flash. Shoot, one or two will be enough. Half of the macro is taken with a small aperture. I think the output at 1/4 is generally good.
