The idea I found good: no additional remote control key finder, which I might not find ... The installation and setup of the app was very easy, so everything Paletti? The test brought it to light. At first I thought it does not work, while the box was only on the device, muffling the sound! In the quiet room I places the key finder from 2-3m distance, if I know where he is, you can hear the call no. To search, ev. In the car on the road or in the office when another speaks, absolutely unsuitable!
