Works flawlessly. Functional advantage over the IR trigger, the radio control with a tried out to date range from about 10 m with oriented forwards Canon EOS450D, even going through closed doors. There is certainly still merh it.
All functions (focusing, triggering, Bulb) available.
Qualitative execution also OK
Bezgl. the attachment I Personal. not a problem because the receiver is so light that it "dangle" on the Cam can.
It was this even a German translation of the manual, but you do not need: batteries (included) pure, plug in the Cam and Los gehtŽs.
CONCLUSION. Recommended!
