Summary: Use SD cards only. The newer SD HC cards did not seem to work for me. Also, make sure your SD card is formatted using FAT and not FAT32. I just bought a 4 GB Transcend card and it came as FAT32. The player can only read from the FAT file system so I had to format the card before using it.
Summary: For playing MP3's this is the best unit I have found. Sound quality is awesome! And even though I bought this unit (I bought one for my daughter as well) 2 years ago, it continues to impress me. Yes, the user interface isn't as flashy as an ipod, but it works and the unit is rugged.
Summary: Hey I've had this mp3 player for about a year and it works great. The Creative Muvo is super tough and work great if your out running or whatever. Even though it's water resistant they don't suggest dropping it in the water, but i've dropped it in a river once and it works just fine.
Summary: When I bought this unit, the label said it accepts 512M card. Then I saw some customers' comments that it accepts 1G card. I just bought a 2G SD card (...) and put it in--it works like a charm. So now I have a total memory of 2.25G, good for 40 hours of music!
Summary: I purchased this MP3/FM player to use while I run outside. What I wanted was a player that had MP3, FM and a stopwatch and was weather proof. I don't like to wear a watch on my wrist while I run.
Summary: After reading the experiences of other reviewers here i was persuaded that my Kingston Elite Pro 1Gb SD card would work with this player, and it does! Decent sound quality and replaceable AAA battery makes this a good buy.
Summary: I've been running with a cross-trainer CD player for many years, but it was starting to wear down and of course it lacked the features of mp3 players. So, I began researching mp3 players specifically for use with running. I held out for a while because nothing seemed to meet all my needs ...
Summary: I agree with all the other users on this. It's almost perfect for the price ($70 frys, no rebate). I came from an rca lrya which I liked, but had many wishes that this unit covers nicely. cons: ---- The volume controls give me fits. The controls feel a bit spongy.
Summary: This mp3 player is really nice. The buttons are a little small, but all of the features are really cool. I esp. like that there is a countdown and a timer within the player. I Especially like that you can add a SD flash card up to 1gb even though it says 512mb.
