Query: great bang for your buck

I got this with the intent of using it on my upcoming vacation. The battery life was great. I got a few days use out of it before I had to change the battery. Using the software was a bit of a challenge, but thankfully you can just drag and drop the songs you want right into the player folder. You can even make folders of music and choose between those as well as the songs within them. Great little player. Glad I bought it.
