I ordered a Tecsun PL-390 from Amazon last June. When it came it was in a carton with all text in Chinese and the enclosed owner's manual was in Chinese also. I was able to download a copy from Tecsun in English, but I haven't found it to be easy to understand at all. I have been disappointed in the shortwave performance, which was my main reason for ordering it. I liked my old Radio Shack DX-392 with cassette tape recorder/playback better; of course it's much larger than pocket size, and the Shack doesn't even offer anything similar nowadays.
I have not tried hooking the PL-390 up to an antenna yet. It will probably do as well as they claim, and it does do a fairly good job with nearby FM and AM broadcast stations as-is.
