I'm here to introduce OSIM iGoGo!
It is a massager that comes with a built in MP3 Player. It has two wireless massagers and could expand to four so that you could have more options to place the massagers to massage. iGoGo is also hands free, you could do other things at the same time with the massagers and listen to songs with the MP3 Player anywhere, anytime!

Comment are, it is convenient as you could listen to songs, having massagers to massage and do other things at the same time. So it also saves time!
