Have the product tested and can recommend it unfortunately only as a toy. My daughter came with the operation well zurecht.Das device fits comfortably in your hand, is lightweight and easy to stow. The best she liked the Anklingel tone. The range of the device leaves much to be desired. One must almost have eye contact to ensure receiving. This is certainly not the sense of walkie-talkies. The quality of transmission is not ausreichend.Fazit for a halfway reasonable communication: sent back, now try the PMR from Audioline.
