I purchased the TX and two transceivers to drive flashes SB-800.
The operation manual is good
The operation is against random enough TTL.
I can take multiple pictures without problems and suddenly flashes will trigger a full power without knowing why.
For a slightly more rational operation, I desactivé layouts flash standby, off the zoom control and I make my focus on the central point only.
I also disconnects all wireless devices in the home. (Livebox ..)
By taking these precautions, I feel I have less worries
