Unfortunately, everybody jumped on the Baofeng bandwagon and started making/selling their own versions of it, even though they all have a Baofeng nameplate. There are numerous "knock-offs" floating around out there .... to this day.
If you happened to get your Baofeng radio from BaofengTech, a US dealer in these radios, you'll actually have a decent one, and for next to nothing in cost outlay (the reason we got a Baofeng in the first place).
You'll know *your* Baofeng is somewhat reputable if, when looking under the battery cover, you see an "FCC ID ..." number; this tells you it actually meets FCC requirements for the type of radio it is (usually a commercial or HAM radio). You can look that ID up on the FCC website, and further determine that it is licensed correctly.
So, if someone is talking Baofeng, point them at BaofengTech for the reasons above. I recently purchased their DMR-6X2 radio, a Baofeng model (digital and analog), as I look into all this digital radio stuff, and try to solve distance problems (as in repeaters and foothills not cooperating with each other).
