After using it for 3-4 hours, I think I made a mistake.

Pros:
Drag-and-drop is slick and easy
Dual puropse (w/the JumpDrive on my keyring)
Small form factor
Standard batteries (not proprietary)

Cons:
Volume not loud enough (have to re-process mp3s before I load them)
Earbuds are low, low quality
Sound quality is marginal, even at 320Kbps w/good phones (or on my Bose system)
Navigation is confusing at best, silly at worst
It does not remember the last song it played - starts at the beginning of the playlist on power-up.
Needs clip, pouch, lanyard, etc.

I wish I'd have paid a little/lot more for another brand of MP3 player. It's a decent stop-gap solution if you need something very economical and already have a JumpDrive Sport. It's a lousy solution, in my opinion, if it is going to be your only/primary MP3 player.

Overall I'm really happy with this player. It's very inexpensive, expandable, and having the separate jumpdrive makes it extremely flexible. This player is great.

I only have two complaints about it.

1. The files you copy onto the jumpdrive aren't necessarily played in the order you expect. It turns out that the files aren't played in the usual alphabetical order. They are played in the order they were copied onto the jumpdrive. If you copy entire folders, the files aren't necessarily copied in the right order. To get around this bug I wrote a short Perl script that sorts the files and copies them in the correct order.

2. There is no really good way to bookmark stuff (yes there are bookmarks, but only per file). I listen to a lot of audio books and it would be nice to be able to set a bookmark per directory in addition to per file. I have to write down where I left off and skip to that spot the next time I listen.

While these issues are somewhat annoying, I would still buy this player if I had to do it over again. It's a great little device.

I am a poor college student trying to save all avaliable money for a laptop, so I did not want to go spending much on a mp3 player.

The user guide:

Suggests that one may drag and drop music onto their jump drive in order to add music. Well, it doesn't work, at least not for mine. I sent my first Jumpgear back b/c of this problem. It just keeps freezing up.

They sent me a replacement (and btw, the only proof of purchase you need is a print out of your order history from Amazon with your name on it) and it is having basically the same problem. I finally decided to try the alternative method for transferring music to my device (via sync on the Windows Media Player) and it seems to work just fine. At least for now.

My only remaining complaints:
1 - The display on the lcd, when you transfer via sync, shows file names such as 06Reme->.WMA and 05Trah->.WMA instead of entire file names, so unless you are just good at guessing, you really don't know exactly what the song is that you are selecting to listen to.
2 - The off button is hard to fine unless you have done your research, I just let mine die through the power save for the firtst few weeks. You can turn the device off by holding down the "play" button and waiting for the message "goodbye" to show up on the screen
3- I wish I could drag and drop!!! :'(

Pros:
1 - Does exactly what you need it to do- play music. I will probably get a more expensive mp3 player one day, but this will definitly satisfy my craving until then
2 - Ultra Portable- More portable than an IPod. I can easily put this thing in my pocket with room to spare.
3 - Good customer service. I had lost my original packaging, and receipt, but they still took my first one back and replaced it promptly.
4 - Cheap, Cheap, Cheap. Great for the penny pinching college student.

go to lexar's site and they have a case for it

I was looking for a battery operated MP3 player that had the max storage that I could get. Non-batteried players require a wall source to power up, which for travelers/hikers/distance people is not readily available. Using the player with a 1 gig Jumpdrive, I had the kind of storage I needed to put a huge amount of songs in my pocket.

Unfortunately, the larger the capacity, the more its main drawback stands out. 200 to 400 songs is nice, but if you have to remember which one you played last in order to skip forward to it every time the unit is powered up . . . much too primative for the market today. Best for 24 hours of sea shores, rivers or rain storms, but not albums.

Otherwise, good sound, sturdy construction, and long battery life. I really wish I could give this player 5 stars, but if you keep a pencil and notepad handy you'll enjoy using it.
