Query: Please don't buy this!

For your own good, do not buy this! if i could have given it 0 stars i would have! It drains batteries very quickly, i could only put about 3 songs on it at "cd quality" (which it wasn't) and the songs got messed up and interchanged. I have a mac, so i couldn't upgrade it because "it currently does not support macs". it doesn't come with mac software, that u had to download from their site. i tried to download it many times, but it didn't work! the quality was horrible, i had to turn the earphones a certain way to hear anything at all. i desperately wanted an iPod, but couldn't really justify spending [amt] for it. I should have after all. This mp3 player...!
