I have held for a Macro Speedlight out for quite some time. That to my Canon EOS 7D, Canon matching original part was and still is to me for my now and then made photomacrographs clearly too expensive. It may be that this device is higher quality, but that is my opinion of all proportion to its price. After some research on the Internet, reading various reviews on this subject, I came with a provider on the Bilora model which as it turned out later, Identical to the dried product. However, the research revealed a price around 20 euros great price advantage for the dehydrator. When the unit arrived, I immediately installed it using the enclosed adapter ring on my Objaktiv, inserted 4 rechargeable batteries Ansmann from the Metz flash and verify that after switching on the ring flash, the camera software detects this. No Problem! The appearance of the flash unit is a bit "plastic way", but since I do not intend to throw the device through the area, but rather carefully Bypass usually with my photo utensils, which plays only a subordinate role with me. Importantly, the enforcement of its function and the flash, so show first shots, he does properly! Therefore my good value for money and 5 stars.
