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.
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.
This player was definitely designed to assume 3 year olds

Excerpt: The Sandisk Sansa Shaker is what defines a truly unique player that would redefine the meaning of MP3 players. Upon looking at the player, it is hard to miss it, due to its odd shape, which bears a resemblance to a pint glass. Despite the shape, it is rather ergonomic to hold and use since its buttons are placed in a relatively convenient place. It allows you to change tracks simply by shaking the device either left or right.
