Partly inert, some recipients verabreitet sloppy, battery FB from the outset empty

Use this radio button to the on / off of shelves / cabinets and ceiling lights. Installation absolutely easy, unfortunately the receiver are assembled sometimes very sloppy. In case a hole in which a button befindent for training, which is, however, partly as slip, which is a really difficult press. But good for such a low price you can not expect perhaps.
The response to the FB is sometimes very "lame" and is sometimes done only at the third or fourth pressing the power button ... am superior, but prefer to invest a little more money, I would not buy it again.
