Comments about Elinchrom Elinchrom EL-Skyport (ELS) Transmitter ECO (just fires, 4 channels, no groups):
This trigger works well with the Dlite 4 kits that I got. Did not take very long to get working and is consistent and reliable.
Only has 4 channels and does not do groupings like the other model.
If saving $ is a priority, then this is the trigger to get. But if you need the groupings...this is not going to suite you.
