Very fast delivery, properly packaged. Thanks to Amazon employees! The flash does its job well done - great alternative to expensive brand appliances. Was tried with the Nikon D7100 + Tamron 90mm F / 2.8. The results I then compared with its of Speedlight SB-910 and found that I did not really need the ring flash. At 90mm macro lens, the distance to the object is large enough (even with 1: 1) to comfortably super results to educate with the matching shoe mount. Defies the full 5 stars for an uncomplicated, creative and inexpensive product.
