In the city, they are almost useless due to the congestion of the air at factory frequencies. In a large city, they will only go for communication in buildings. Walkie-talkie for communication up to 1 km. Bought, tried and wanted something more professional. With its pros: Strong body. Ease. Simplicity. AAA batteries. Ability to set up a group on one channel. Cheap. Has some cons: Fixed frequencies. There are 8 channels in total. Low power and inefficient antennas.
