ok, here is an update:

So far so good...as mp3 player (hindi ko pa gaano ginagamit sa cd's kasi merun cd player yung oto ko) satisfied ako.

jWIN is made in China pero it doesn't seem to be the cheapo ones. They have a website. jWIN

It is probably a second hand (I'm not sure) dahil masydong ngang mura...pero malinis pa yung nabili ko (and so with the other paninda)...no markings na second hand.

As for the picture of the unit (pasensya na malaki):

Walang box and manual pero I was able to download the manual from their website.

The audio is good with the stock sound set-up of my 2din clarion (sa dmax) with the tape deck pati rin sa kasamang headphones nito.

It has a 120sec anti-shock system so so far wala akong naririnig na skip. It is running on 2 Alkaline batteries and so far I have probably used it more than 2 hours total na pero no problem.

Will further observe the unit how it goes - I'll burn me some homebrewed MP3's and CD's...we'll see how it plays CD-R/RW.

I haven't successfully tried plugging the power outlet though...hindi ako sure kung gumagana, pero it have provision for rechargeable batteries instead of plain batteries.
