Summary: I had a Sansa 1 MB player - same legacy device just more storage and it lasted over 6 years. When It died I was really bummed out - I liked the fact that it was battery operated so no worries about not being able to charge when traveling, just pop a new batter in, it was drag and drop which I love. It suits all my needs for a portable mp3 device. I saw this on ebay and thought I'd just replace it and it died with very little use - will not turn on.
Summary: I like the ability to use a SD drive to play my MP3 files. One of the things that I find wrong with using this MP3 Player is that the thumb control appears to have a tendency to jump, giving you weird results. Overall, I would have to say that this is a very handy device.
Summary: I had been using my phone to play mp3s, but when I got to the point where I was listening to music at work for about 8 hours a day, I found that my Windows Mobile phone's rechargeable battery left much to be desired (a phone that plays mp3s is great, but sometimes it's best to have a device that has more focused goals!). I decided to get a new device specifically for when I'm at work.
Summary: Purchased this for my 7 year old who's previous player (not a SanDisk) had quit working. Wanted something easy for her to use that would hold enough music to take her through trips around town and vacation road trips. This player is SO easy to use! Simple to add files to, and easy enough for her to use that she had it figured out within one trip. Sound quality is actually pretty good, and battery life is surprisingly long.
Summary: I have very specific needs for an MP3 player: SD card slot, field replaceable battery. Easy to pack/carry. This series of players meets both criteria. Pros: Accepts up to 2 GB SD card. Operates for 4+ hours off a single AAA NiMH battery. With a solar charger and a few AAA batteries, will run almost indefinitely in the field. Very light weight. Very inexpensive. Easy to navigate menus. Relatively quick fast forward. Sleep and auto-off functions to save batteries.
Summary: I can not compare this MP3 to other brands as this is the only one I have ever bought, but I can give the reasons I picked this MP3 in particular. 1. Cost - very reasonably priced. 2. Accepts SanDisk memory cards. - I can use a card of any size. I like to use one card to record music on, one card for podcasts of radio shows, another card for self help meditations and last but not least one card for books.
Summary: I had a unique use for this player... I purchased four of them to run 7/24 for our in-home music system. One has Jazz, One has Rock, etc... Since these units have an AAA battery, I simply replaced the battery with a dowel with two power leads to a 1.5v dc transformer and "presto"... Full time music. It also has a memory slot so if I want to change the music, I can change the mem module rather than plug the unit in. VERY convenient.
Summary: This little mp3 player is wonderful in that it is expandable using SD cards, and everything about it is standard issue. If you have any portable electronic gadgets chances are you have the cable (just a usb --> mini usb), and SD cards are about as standard as they come. Clinging to all things standard is also the downfall of the device as SANDISK has forgone a rechargeable internal battery and instead this device runs (for something like 15-20 hours) on standard AAA's.
