If it walks like a Baofeng UV-5R and quacks like a Baofeng UV-5R, then the Yuehong YH-A8 is a Baofeng UV-5R. Discussion of this identity confusion is here.
Given the Yuehong website has this image on their main page (note the Baofeng label) and that Baofeng radios dominate their product page, I'm thinking the YH-A8 is nothing new.
