Review on 📞 Retevis RT21 Walkie Talkies: Long Range, Rugged Two Way Radios for Adults – Case of 5, Ideal for Commercial Construction, Warehouse Security and More! by Bryan King

Great price for these radios. It's good to have headphones for everyone, although the microphone attached to the headphone cable isn't the best sound. The internal microphone in the walkie-talkie sounds better. It was very difficult to find the range for these radios. They worked great in close proximity, for example around a few buildings and through 1-2 walls. When I took them up into the mountains, they found they didn't work beyond a few miles. So don't expect to use them over long distances. They sound great up close. The battery life is excellent.
