The negatives: A feat of engineering are not those parts, and one wonders what this man impels one on and to spoil for visual good technique with incomprehensible nonsense. - A / Ausschaltschieber located at each Aufsteckblitz after assembly including - so if a flash it is possible to the device no longer on / off. - A trip through the button on the unit is not possible if the device is not plugged into the hot shoe. What for?!?! So you have to carry around the whole camera to measure the flash exposure?!? - Used as a camera shutter must be the unit not be placed on the hot shoe because otherwise it does not work anymore. Also very clever ... shall I then glue to prevent it from dangling?!? - Recording closely for batteries. very tight. - No screw for mounting / attachment. - No lock on the hot shoe mount. Although does not fall, because it fits very tightly, but this is not certain.
The positives: + Extremely long battery life. 9 months for weekly use is even an announcement. + Small and light, easy to transport. + Huge Range.
