A friend bought the wireless one and because of the not so big battery (although it charges everywhere with a Power bank) he sold it to me. The Wireless has a very good signal everywhere, I consider that it serves perfectly whoever buys it, I work in the fire department and it helped me a lot... I made this review because I wanted to write... I went to a fire, it fell, I ran over it with the car because the fire closed me in, the fire passed over it, melted a little the back clip that holds the wireless, melted a little the battery cover, the battery came out of its place... I wiped the wireless, put the battery back in place and continued my day and it worked normally... Nothing happened... Well done Baofeng.
