Olywiz Walkie Talkie Rechargeable Two Way Radio Long Range Li-ion Battery 1800 mAh UHF 406-470MHz HTD827 2 Pack

I would not recommend buying these. The very first time I used these Walkie Talkie was this past Saturday. As I was leaving the driveway going to church I called my wife inside the house to close the garage door. She said she couldn’t hear me. I don’t know much about radio, but this one it’s not worth buying. Cellphone is always the best. Any suggestion of how to operate these Radio?
