We bought this baby monitor based on the reviews. It works flawlessly within a radius of about 20 meters in and around the house. Is reassuring that there is a loud hooting from when you move away from the range of the transmitter. The reception is OK again, we hear that the child is awake but not accurate, which is actually not necessary. Unfortunately, the receiver's rechargeable battery makes fast limp. Meisst we use it on the basis of this, without holding the receiver about 1.5 hours.
It works, sure there are better and higher-priced equipment, but for our needs it is sufficient.
