If you own a Canon 50D I have for a replacement for the overpriced original part of Canon. Unfortunately, I was in my Shopping somewhat premature and did not get it, but that is not replaced this part similar to a TC-80N3, because it has a 3.5mm plug (like the headset). Anyone looking for a TC-80N3 spare, this part should not buy - but who an EOS 60D, 600D, 1100D, etc. has, here is probably not wrong.
For product: I have not been able to really try, but a solid impression made it anyway. The only blemish was the big button that was already a bit shaky. I had the impression that you could use him for good. But the feeling of the release button on the camera, he has not definitely.
I deducted a star because despite described delivery no German instruction here was (purchase date September 2011),
