I own the Round Flash for only a few days, but he has already produced many outstanding photos. Very easy to carry and use, but (understandably) a bit bulky at the camera. However, this is the only thing there is to complain, but what does not really bother me. If you know what you're doing, virtually every portrait is a direct hit. I have previously experimented with an O-Flash, but this produces uneven lighting and leaves strangely shaped catchlights in the eyes ... as opposed to the Round Flash, which always beautifully illuminates a large area and uniformly, and perfect catchlights generated in the eyes. The sample photo, that is the morning arose spontaneously without any preparation to 6 in a club, conviction should be enough.
