Summary: It's amazing to me that there could be an MP3 player that allows one to corrupt it by simply uploading slightly more data that it shows. That's what happened. Pathetic. Playng volume is weak, the display is easily cracked, and now my son's player is a useless paperweight.
Summary: I have the c140 and c150, and both are very frustating. The c150 took 10 hours to fill the 2GB of memory. Now the C140 is acting up. I can not add or delete anything from this unit. With Sandisk support and trying to format it still no luck. A huge waste of time! And also money.
Summary: I've had my C140 for a few months now with no problems - no distortion issues no trouble moving files to it. HOWEVER, with doing absolutely nothing to it, my C140 is now frozen. I can power it off but it's as if the hold button is on.
Summary: I bougth this player almost one year ago. From the first minute I was dissapointed by the sound quality. Compares with old cassette player (not even with the worst cd player). Battery average life was under 10 hours.
Summary: We purchased this product as a Christmas gift. The MP3 player arrived, but did not include the very necessary CD which contains the "Sansa Media Converter" software so that we could put pictures onto it, nor the even more important "User's Manual.
Summary: I've had my Sansa c140 for just over a year. Several times it has locked up, and I've managed to get it working again. Now it won't connect to my computer, all text is missing from the menus, and tech support isn't responding. (Being out of warranty, they probably won't.
Summary: Used the player for about three months. Worked good. Then one day when I turned it on, it froze up completely--pressing the controls had no effect on the display or operation of the player. I tried a new battery. No effect. The only way to turn it off now is to take out the battery.
