Uniden GMR1038-2CK 22-Channel 10-Mile Two-Way Radios are absolutely horrible!!! I was just so disappointed with this product. If you are in an open field these will work fine but if anything is in they way - buildings, trees, other obstacles then they will be static or just not work at all. And the batteries do not last long at all! Even the rechargeable don’t last long with this product. Although they are a great price being only $30 you mind as well just spend your money on two Megaphones because they would probably work better!
