Very good. The anti-skipping is the main reason I purchased this model, and I must say, it doesn't disappoint. Right after I put the batteries in this thing (not included by the way) I tested the heck out of it by shaking it every which way while playing a CD. Right-side-up, Up-side-down, sideways ... you name it ... I shook it as hard as I could and couldn't get it to skip once. Not too shabby. The sound is pretty good, not incredible. Oh, and that color on the outside (of my model anyway) is dark blue ... not black. Not a big deal, I really didn't care, but in the ad it looks black and silver. Overall, good item. Very pleased.
