Summary: I love sansa products and I brought this one for my mom it was ok but i didn't like that the batteries seemed to drain quickly. No matter if they were duracell, energizer, or a generic. they all seemed to be drain too fast.
Summary: Good: Easy to copy music in MSC mode, FM radio Bad: Clunky interface, MTP mode only works with Media Player (and poorly), AAA battery drains fast. Bottom Line: I bought this as a backup player while I await my Zune trade in to arrive. For the used price I paid, it was worth it, but I think there are superior brands out there for those looking for newer small gig capacity players.
Summary: I got this to play music in my car and works fine for that. The battery life is pretty decent. It's easy enough to use, shouldn't need to read "the book". It looks good, the display is very clear, sound is good (playing through my car speakers) and it's also compact. What I think could be better: The way you store the songs is limited. It should be more flexible then what is given as choices (album, artists etc.).
Summary: First, the good: I got this player for $35 plus shipping, which is a decent deal. It doesn't require special software to work, although it can be set up to use a sync'ing media player like WMP or Rhapsody. It recognizes M3U playlists, and most importantly of all it has auto-resume play. This is critical for me, as I use it for listening to audiobooks in the car. The resume has worked every time, even with a battery change in between listenings. It has good battery life.
Summary: I liked the c140, especially its clear display, but it won't play Audible's audio books, as advertised. I tried two players (I returned the first for replacement, since SanDisk thought it was defective). Audible's books could be transferred to the players,albeit very slowly, and they usually appeared on the units' displays, but they couldn't be played.
Summary: I already had an iPod but needed an even smaller player for travel, and wanted a device that I could run on batteries even in countries where I can't rely on stable electricity. This machine fit the bill and has been fine thus far--as others have mentioned, it's easy to load and operate, and very lightweight. It also has better FM reception than the stereo with antenna does in the same room.
Summary: Its an okay mp3 player. I like it. Its easy to use and easy to travel with. What I don't like about it is the triple A battery thing. I use my mp3 player A LOT, and I go through so many batteries it isn't funny. I'm thinking about selling it and getting a different model. Maybe one from the Sandisk Sansa e200 models. They are better and guess what?! They have a rechargeable battery. So if you don't plan to use this mp3 player often then by all means buy it.
Summary: I bought the C140 solely for Rhapsody-to-Go music. It's cheap, ultra-portable and plays "to-go" music without any problems. In fact, the CD that comes with the C140 includes Rhapsody Jukebox software and required Windows Media Player 10. Set up was easy and navigation on the little tiny screen was fine (although graphics are not clear and appear in low-resolution). I wouldn't want to use it for viewing images which it is capable of. Having the FM is a plus.
Summary: Sehr groß und dick für ältere oder grobmotorige Menschen (bitte nicht als Beleidigung sehen) gut geeignet. kann nicht mit MiniUSB aufgeladen werden, geht nur einen 1,5 cm breiten Ladesstecker der am USB angeschlossen wird. Ich habe in deshalb nicht in betrieb genommen und kann daher keine Ausage zur Bedienung und Funktionalität sagen.
