The remote control is processed according to the price, plastic housing with foil on top, covering the components. Wet should be allowed to be by no means the good thing, because then it would be over quickly. Also, one should be careful in the film at the edges, so that this does not become detached. Both, however, at the price acceptable circumstances, especially when I doubt on original Sony that they would withstand more than a few drops of rain.
The functions of this Department are exactly what I was looking for. Immediate release and 2 second delayed shutter release function properly, you must not forget to inform the camera beforehand that you want to trigger with the FB. The receiver in the camera is housed in the handle bar end and therefore easily accessible from the side, so that no one should be in the picture itself.
For the price, the FB is definitely a bargain, because so much already costs a replacement battery for it. This would also not the end, when the device must not have long life, I can not review now.
