get the NI X1 case, this is just a 2 piece cutted foam with a zipper2 holes, 1 in the back to let the X1 fit in, and the other in the front to make space for knobsit does not offer the kind of protection i was specting from a "HARD CASE", this is not even hard at all (in the parts with no foam, around 60% +/-), in the knobs area u can feel the "click" made by the 4 wheels/knobs with very little pressure on it, even holding it hard enough to handle good will click, at thats way its covered by a very thin "something harder than cotton".the materials feels good, the zipper works fine and looks like its going lo last long,
