I had 3 requirements:
1. Display, so I just can select folders that i just want to hear
2. Long battery life (20 hours or more should do the trick)
3. A clothing clip
Thus, unfortunately, was no longer eligible Sony Walkman.
For SanDisk device:
1. Display
The display is available and good. The menu is to act quite clearly and well. However, the folder names that I forgive, not adopted. If my folder to eg rock music hot, he is at once the 250 millionth This is very confusing!
2. Battery Life
From the battery life I'm really disappointed. The battery lasts just 10-12 hours. This is really annoying because I have to charge it frequently.
3. clothing clip
The clothing clip keeps fine. So I am very satisfied.
Conclusion: The sound of this player is great and the clip holds super. However, other points annoy me very much. Moreover, he was not exactly cheap. Once again, I would not buy this MP3 player. I wonder if I still buy my Sony Walkman. Pity!
Update: After less than a year, the clothing clip is canceled.
