GSI Outdoor Waterproof Entertainment System for Bike/Motorbike/Cycle/Bicycle - Sleek Aluminum MP3 Player, Powerful Loudspeaker, Built in 2GB Memory,

For some reason, when I plugged it into my computer nothing happened. I let it sit and sit and still nothing, then finally the light came on. As soon as I started adding songs it turned off. Now it won't come on at all. Total waste of my money.

This appears to be an inferior product. The operating instructions are written in pidgeon English. At first, I could not access the memory. After getting some songs on the entertainment system, the speaker would not work. Only could use earphones.
