The best purchase I have made in years.
When my 10 year old daughter bought toy walkie talkies she was so disappointed that they didn't work as expected. I searched for a more practical solution and came across the Uniden UH45 four pack. Now my daughter can talk to her two sisters, with me listening in, from quite a distance. The real benefit is being able to talk to all three of my kids while riding our bikes or playing in the park, no more yelling at the top of you voice! The fact that they are different colors allows each child to have their own radio and look after it themselves. The ability to set individual call alerts give each child an identifier which my kids use before they start talking. The compact size means they can keep it in their pocket or clip it to their bike. Managing the batteries is simple too, just install rechargeable AAAs and simply plug in after use.
