For buying this article I have decided after looking through the reviews. The delivery was then faster than announced. After receiving the parts I've unpacked the same. The manual is in Chinese and English. Due to the numerous photos you might imagine the operation without English skills. In principle you need only insert the batteries and turn on the receiver. The station itself has no on-off switch. The parts have run at all. The remote release I've used several times without any problems. If you use the program "EOS Utility" from Canon to see the live image on the computer the Camera etc., the remote release does not work - there is obviously some lock (computer camera?). Instead the on off switch of the transmitter I remove the batteries after use, since I do not use the remote release day. This takes as the insertion, only a few seconds.
