Bought from AMAZON for my mother and they work great. They sound clean no noise when playing CD's.

These are by far the best quality and most durable dog toy I've found. I don't feel like they should be $25, but that's just me.

Ex Output:
Good Review

Bought it so my son could use the Ipod, after only one day I am taking back for a replacement! What happened to quality?!!! First time ever, returned a product of this type, first time! The screen started randomly changing colors, like colors were being displayed that had nothing to do with the color itself, and then blue dots all over on each pixel. Very disappointing! Had high hopes from what others who purchased said about these items. Maybe you should look elsewhere...

Ex Output:

Bad review
