Summary: I can't really say anything about sound quality as far as this product goes, as it was defective when we got it. The power button did not work so we were not able to turn it on unless it was plugged in via the USB. I am not just giving it two stars because the one we got was defective, but because it seemed somewhat fragile to me. For an MP3 player that is meant for kids, it just didn't seem like it would hold up well.
Summary: Design of the bottom battery/memory cover is just bad, comes off every time and held with unit by a string, ended up cutting string and removing botton cover entirely. Only reason I got this unit was the built in speaker for my 8yo daughter. Burns through regular batteries very quickly. Because you cannot jump directly to songs, get the smallest memory model there is, your child will not be able to access 100's of songs.
SD memory card lost all data after 3 days of operation

Summary: Unit worked OK until the first battery finally got low. Upon battery replacement, I noticed an error signal (drum up, then drum down )occured every time I tried to power it up--the Sansa 1G SD card had lost all data. Had to reformat and reload my songs back on the card--then it worked OK. The bottom cover can easily fall off if not installed just right--poor design there. Loved the little speaker on top though--that's pretty cool.
Summary: The Good: The sound quality is good both through ear buds or the speaker. The SD card it easy to load with music straight from a card slot on the computer or via the USB cable. AAA battery last about a day. The Bad: I bought this for my handicapped daughter who has trouble with small buttons and labels. A large on/off button and shaking to change songs looked ideal, but.... To change songs you actually have to hold in the on/off button and then shake. It's hard for me.
Summary: Even though the technical details on this page specify the term "USB 2.0", this is a USB 1.1 device (which is a lot slower for transfers). This might be a good gift for kids, but given the price it is better to look for other cheaper options...
Summary: I bought two of the shakers for my kids (ages 4 and 6). I liked the design and ease of use. The kids had no problems using them. They really liked the two headphone jacks and the fact that they could listen to it without headphones. My biggest complaint is it is hard to turn off (or determine if it is off). We found ourselves burning through batteries. In addition, everytime we add new music, the old music erased.
