It's too early in my usage for some assessments but this product appears to be well made and it certainly works well producing well balanced light coverage. Although it doesn't possess massive power (GN15) this isn't a problem because this unit is for macro work. Having said that, it will double as a normal flash in extremis although a normal bounce-head flash would be the preferred option for most. It is supplied with a variety of adaptor rings to suit various lens filter mount sizes, which is good but considering its primary use is for macro photography it was disappointing to find that it did not include one to fit a popular macro lens, namely the 105 mm Micro Nikkor (the one I use most) fortunately, I also use Cokin filters and I did have an adaptor ring for their system that not only fits the Nikkor but also is a perfect fit in the ring-flash unit so if you find the same problem, that is a simple solution.Time will tell whether this product's performance lives up to first impressions but so far I have only good things to say, other than that one small caveat, and when you consider the cost of similar kit from the likes of Nikon and Canon it has the potential to be the ideal purchase decision.
