This baby monitor is very effective, good range, no interference, clear sound sensitive microphone and just what it takes. The distance from the projection control functions of stars on the ceiling, lullabies are top; everything works fine, the receiver battery takes quite a load. Even the speaker was correct rendering when connecting an MP3 player and all remote control, and allows continuous reading or programmable timer. The night light is not very bright but .... c is a pilot. I recommend this article.
