Class ...... 50

Class, no question ....
have already bought two of these devices and am very satisfied
Benefits:
1. already built in transceiver
Here to owners of station RF602, change the flash first,
because standard is set by the factory of the recipient 603.
Among the various types of transmitters:
I recommend to be the slightly older model 602, which
a transmitter and a receiver needs.
Type 603 is both in one, but with a huge disadvantage
no thread bottom of the hot shoe !!!

2. very good and the small setting of performance all the way down to 1/128
who makes macros, or the flash time as a fine sidelight, backlight
needed this possibility is greatly appreciated.
There is the possibility of fine subdivision not only
the usual jumps from 1/128 to 1/64.

3. Configuration:
Here I like that I can influence the sleep modes, or even shut down.

4. Accessories:
one foot is on board, it needs, however, because of the hot shoe is not threaded,
Deflector and small pull-Bouncer.

Disadvantage: English manual
