Absolutely fair price / performance ratio and good quality

Primarily, I use this to trigger the camera. Also works with compact flash, which I think is great.

Otherwise, I can only agree with the previous speakers who want to TTL or needs, of course, more needs to put on the table, but sufficient for my use this remote trigger.

Super I find, as has been already said that conventional batteries (AAA) fit into the radio trigger, for such has always at home.
