Good lightning

I bought the flash for my Nikon D5100.
The internal flash of the camera is something lean and I've always wanted an external flash
as an accessory.
The flash works great. The first test images have worked quite well, though I still
Beginners am.

Positives:
+ Good workmanship despite Made in China
+ Works with AA batteries
+ Flash head rotating and can be increased
+ Very easy to use
+ Good manual in German
+ Works perfectly with the Nikon D5100 together
+ Beautiful bag and useful accessories included.

Negatives:
- The arrest of the flash head is pretty annoying and hakelig initially infinite but is to do with a little practice.
- It contains no batteries included. Who wants to try the device, so it must get what for now.
- Arresting the hot shoe of the camera looks a bit shaky, but it is not.

Remarks:
The power switch must be unlocked only with the locking button in the middle, if you want to turn on the master / slave operation.
Used for the normal, the switch can be switched even without the button in the center.
The distance reading is only displayed when the flash head is in zero position and absolutely straight.

I'd get me the flash at any time. Should I again need a flash as a slave flash, it is also
an SB-700 are.
Price-performance is justified, though not a bargain.
Full marks.
