Hello everybody. So long about (260) ... and yet bought. The MB-D14 st actually a useful part. Fits comfortably in your hand and asks to which a second trigger. The second product is an excellent idea. But in my MB-D14, there are problems with the AA batteries used. After switching center in it at work suddenly adopted the indicator for the battery to handle the display on top of the camera. A wiggle contact, it is not faith. Because after removing the AA bed maturation cassette, and insert the renewed Lights regained control LED and the indicator on the display is as resist. But not entirely (almost empty) and not long. A short time later, the story always repeats resist. Of course I checked the voltage of the AA batteries. The is OK at all 6 batteries 1.5 V. I appreciate the Nikon D600 has a problem with recognizing the AA batteries (which are not Nikon product). The original Nikon battery cassette is new and circuits such at all. Too bad, so what had yet to be known at Nikon? Two Nikon battery cartridges were dear to me. This because only 4 stars ... But what soll` s, not back because I send the MB-D14. And 6 AA batteries are to me as so to carry too heavy rum. And also too cumbersome. Interestingly if anyone, on the device, the same gemärkt has?
