Full and cheap Kit: PERFECT

My camera: Canon EOS 600D
Many cables are present in the package in order to permit the triggering of the remote box.
For my case, I have to use the C1. It works perfectly. 3 positions on the receivers
(OFF - Flash - Camera) and 4 on the transmitter (OFF - Flash - Camera - Delay). At halfway, it is
developing and supporting fully, it takes the picture. FYI, the "delay" is about 5s.

Photos are not binding because all indications LCD screen illustrations
are not present on this model (see my attached photo). TTL mode is supported by my
reflex enclosure.
Very easy to set one of the 5 modes: TTL - Manual - Strobo - Slave1 - Slave2.
The intensity of the flash in TTL can also be set from the DSLR housing.
Articulation: -180 ° left, 90 ° right.
from 0 to 90 ° upwards.
Retractable diffuser and white tab within the flash.
Green backlight.
WARNING: the instructions are in English.
Comes with cable C3, 2 PC sync, 2 adapters 3.5mm-5mm and 2 cables for flash-lamp,
2 soules broadcasters and 2 plastic diffusers "hard".

Can connect a flash charger from the front (but that's about 350) and no
standard screw on the side (the hole is simply plugged).
