RF123 has always been one of my lowest earners since I started in 2005. They range about 1/5 of iStock earnings and about 1/10 of shutter stock's earnings, with the same images. January was my biggest month in 2016, but that isn't saying much. 1600 images and I earned a whopping $146.00 the whole year. I should say I don't submit much to micro anymore, and haven't for three or four years. I think my images are reaching the end of their shelf life.
