Radioddity R2 Two Way Radio 16 Channels Long Standby Time Scrambler, USB Charger + Earpiece (4 Pack)

These radios really do work well - much better than their low price might suggest. They outperform similar radios that can cost much more. We've yet to experience any interference or cross-channel chatter, since they employ technology to mute unwanted signals. They operate for a really long time on a charge. Take care to switch them off when not in use; there is no pilot light to tell you they're on unless they are actually transmitting or receiving.

Great low cost product
