"good case"
The case is good in that it fits snugly around the player, but is also easy to remove for battery changes. I've been using my case for about two years now and it hasn't ripped or even started looking dirty. I clip it on when I head out for my run, so it does get a fair amount of use and is still in good shape. The clip is good for armbands or waistbands, keeping the player steady and secure. The case doesn't provide any protection for the screen, however, and really should be included with the player. Shipping might be an issue. I ordered it once and it arrived promptly. When I ordered a second one as a gift, it arrived two months late.

"Resistant silicone blue case"
The silicone blue case looks like the same by the time I bought it. Very good.

"Sansa cover"
the cover is an inexpensive way to jazz up the look of the Sansa mp3 player. A good deal.

"Excellent for running"
I purchased this case to use with the Sansa M200 while running. I actually find it much more useful than the armband that comes with the player, because I can clip it to my water carrier waist band, or even to the waist band of my shorts, and run the earbud cord under my clothes so it's not flapping around while I run. Very pleased!

"Fell apart first time I used it"
Trying to get it in and out of a backpack on an airplane, the hard plastic clip tore off and caused another tear in the silicone. Since I was out of the country for some time after, I was unable to return it.
