Summary: Definitely worth what I paid for.
Comment: Pros: Hold a lot of music, very user friendly, great sound quality, very durable, good battery life. Cons are: large (if that bothers you), freezes from time to time, I had a lot of issues getting it synced with my computer. Other than that, It works great.

Summary: Iriver
Comment: Right now it works fine. I've only used it to download music. Wish it came with an adaptor so i could use it in the car. So for now...it works.

Comment: First, there is a small level of computer knowledge required to really use this thing at its full potential. Not much, just the ability to drag and drop files in windows. If you can do that, then you do not have to have your player tied down to any software, you can mix and match file types within album folders if you so choose, something that would melt itunes or windows media. The radio is excellent, the battery is decent, the screen is nice, the sound is very good. It looks nice, survives falls easily. The ability to read text files and record voice is good for students. Plus if you carry this around, and you dont really need a thumb drive.
so why only two stars? Cause the longest I have ever heard one of these things lasting was just under two years. Generally the firmware fails somehow and you can no longer transfer files. The mini jack is not of the highest quality (when obviously the mini jack should be the most durable thing about any portable music player.) If you do get one for like 50$ or something be sure to carry around a small paper clip btw, you will need to reset it semi regularly.

Summary: 3 of 3 I've seen are garbage.
Comment: I own this, and 2 of my friends own them. They seemed like a great deal 2 years ago, better than the ipod of the time. 3 out of 3 are now almost useless. huge problems uploading files. huge problems with hardware. huge problems with sound and playback.
Buy an ipod. apple knows what they are doing

Summary: Works fine with WMP 11 and Vista
Comment: Purchased refurbished 8/07 with my Vista laptop. I like it but struggled with it the first 4 hours, reformatted it (nice feature) a few times using firmware updater program (download from iRiver) and started over. Once you understand it, it is actaully straightforward, but not as intuitive as hoped. Instructions say it works only with Win Media Player 10 but actually works great w/ the latest version 11. My advice - spend time cleaning up Id3 tags (Title, Artist, Album, etc.) before Sync-ing mp3s. Those tags end up being your folder structure for browing the players mp3 folders (by album, artist, etc.). Had trouble prior to id3 tag cleanup, created an inaccesible 'Unknown Artist' folder. My experience, the program that comes with the player for Windows Explorer like-functionality (Copy/Paste mp3s) wouldn't work on both my XP and my Vista laptops (shows 'Disconnected'). Actual Windows Explorer browsing to the player like a USB drive locked my unit up forcing me to push the reset/restart button (with a paper clip) so don't bother, stick w/ Sync-ing in WMP 11. What you save in $$, you'll pay back time spent understanding and making it work. iPod 30 GB more expensive but way easier interface
