The case acts as a second skin over the Clip+, and prevents scratches and knocks (and emulsion paint!) on the surface of the player.
The material is squidgy to the touch, making it a little bit shock absorbent. Seems to cushion the player from damage when knocked off a table or falls out of your pocket.
Overall a good buy, though it doesn't protect the screen, hence 4/5.
(The seller is from California, so the delivery takes longer btw, though still not as long as Royal Mail can take!)
