At the time I bought the parts as radios and they do this job really well. Range is neat, even by very thick walls (for example, they have used in a castle), battery power super, reasonable voice quality and many useful features. In addition, we were glad to be able to use it as a baby monitor, thanks to Vox function - this only works extremely unreliable, so that we do not have our child partially shout to hear what course less important. The sensitivity is simply not high enough. For a point deduction.
