hello , has anyone have experience using this item

http://www.ebay.com/itm/mini-SD-Card-MP3-Sound-Module-For-PIC-Arduino-WTV020-SD-16P-770-/170929162894?pt=LH_DefaultDomain_0&hash=item27cc2c0a8e

can it play mp3 sounds if i plug an audio output to the module? cuz there is another one but it is more expensive, so hopefully the mini sd one can work

thanks for the advice in advance!

I read the datasheet this chip is mono and I think it misleading. can't play mp3 and limit only 10-20sec. file.
