Originally posted by stevebrot They have limited dedication for Nikon and Canon (wake-up only, I think) with appropriate extra contacts, but work with any flash except Sony. The Nikon version is preferred because of less chance of interference from the contacts present on the Canon version. By pleasant coincidence, the wake-up dedication also works with Pentax flavor flash.

Sounds promising. So if I buy 3 units of the Nikon flavour I can fit one on my GR or KP and the other 2 on my Nikon speedlights? And all will be well?
