The ones that I?ve purchased have been 10 watt units. They aren?t really new, I have a couple that I purchased last summer. They are quite rugged, though not weatherproof. They feel like they could be used as a hammer. They do transmit better than the UV-5R. Their battery life is impressive, the radio can be left on for literally days in receive mode.
So, the pros include more effective transmitter, long battery life, and overall ruggedness.
The cons include, significant weight, lack of weatherproofing, and it?s a Baofeng.
I?ve paid under $70.00 for mine. They are programmable with Chirp. I really prefer the UV-9R Pro, as it?s waterproof and dust proof, and it can be recharged directly with a USB-C. Both radios have a place in my radio toolbox, the UV-5R, not so much.
