If you bought a Zoom H4N, this is one of the nicest features to have. I use it a lot when we have rehearsal with a band and Zoom H4N is positioned in the other part of the room, meaning that everytime I would like to record something I would have to get to the device and as it is in the ear level, I'm not able to see clearly on the screen of it. Most of the time I have auto-sound leveling turned on and in that case I just need to set pre-recording on and drummer plays louder parts of the song and then I hit record to start recording. Also light on the left side of the remote (red/green) shows you when you are in no-recording/recording standby/recording mode...
Only downside is the cable, but if all of the band members are aware of it,they don't step on it or pull it with their feet...
