But first things first:
The device consists of two handsets and two charging stations. A charging station (for the baby) is for continuous shop designed say has an overcharge protection. The others do not. Why I do not know probably because the 50 cents would cost more ... We have now in any case always the problem that a single charge exactly does for one night and we then need to charge 8 hours the device and then have to take the charger out of the cradle. What people do not seem to know when Reer that children of the baby monitor is a need also often want to sleep during the day and you accordingly need the device while charging. Say you have to take leave from the charger .... which would not be so bad if it would be a battery without memory effect .... Thus there for the battery history a point deduction.
This works quite well with the connection. On what you have to get used to but is that this device, unlike other baby monitors that we already had, every time arrive when turning on the baby monitor with the parent device typical radio noise. That's not a problem on the day, but quite annoying at night as these noise sounds are sometimes very loud (even if you put the volume to a minimum). But there's also a point deduction.
The build quality is quite good. The design is a matter of taste. If you want to use the device later would be a different color than light blue might be appropriate ...
