"Anti Shock" - I think not,
Verified Purchase(What is this?)
This review is from: GAGS Black Water Resistant Anti Shock Dual Zipped Sleeve / Case / Pouch For All 13.3 inch SAMSUNG Series 9 900X3B, SAMSUNG Series 5 NP530U3B-A01UK Ultrabook....Shielded Zip for Extra Protection (Electronics)
OK for the price but mis-described. As protection against scratches it's fine but don't expect this to help much if you drop your notebook. Only just fits Samsung Series 9 and is stretched tight over the top corners.
