Query: Very disappointed

I was very disappointed in this MP3 player since it's the most popular waterproof available. I followed the instructions, but found water in the screen after two uses & rust-colored water coming out of the holes in the ear buds. The third time I tried to use it...it wouldn't even power on.The player is difficult to use because each button performs multiple functions. Even with the manual in front of me, it's confusing to operate. The buttons are small and VERY difficult to push. The water ear buds are uncomfortable & don't stay in place while aqua-jogging. The screen is hard to read even when it's illuminated. The clip comes off so easily that it's almost impossible to clip the unit to anything b/c it just pops off.I wouldn't recommend this product to anyone for any reason. Fortunately, I've recieved a full refund from the vendor.Thanks to the suggestion of another reviewer, I've learned about Otterboxes. I'll be buying an iPod Nano as soon as Otterbox markets the box to fit!
