My expectations were not overly high: Portable, rechargeable parent, reliability and good transmission quality in audible volume (which is not self-evident apparently). Nice but not necessarily would be a low-radiation transmission.
After two months of daily use, I am very satisfied with the baby monitor.
The transmission and sound quality is very good, I hear my little one even if they do not cry and play with something. Is it around me sometimes louder I can also see from the LED display if sch does something.
The sensitivity of the microphone and the volume of EE, like all functions controlled by the parent unit and the battery lasts several days (when I turn off the parent unit if we do not need them).
The ECO Mode is great, so noise is only transmitted when there is something to transmit. In between the parent part switches off by itself and of course when you need it to.
The display of the temperature is not absolutely necessary but very informative.
The intercom feature is not really necessary but handy from time to time.
So all in all: buy recommendation!
