Handling:
The camera must be set to the self-timer mode with camera to make it work.
From the integrated buttons function each button for direct triggering (S) or the 2-second delay (2S).
The other three keys contained Zoom and tripping (S, S & T) do not work for research on the Internet this seems but rather a general problem of the to be "favorable variations". Apparently you have here but then pick up the original!
For my purposes, the remote control is enough. So if you are from shorter distances, eg in Selbstpoträits with the wife / girlfriend / husband / boyfriend), NEN want to shoot some nice pictures, this is very helpful.
Processing:
The processing of the remote control is surprisingly good, the keys respond well, it wobbles nothing on the operation and the whole is very compact. The very small size is very convenient, so you can see the remote theoretically stuck in your shirt pocket to them at any time to have at hand. So do not take up much space :) off.
Conclusion:
For the offered low price the price / performance ratio is in my opinion, totally okay!
