This was one of the best purchases I've made all year.  I am 100% behind these AmazonBasics products.  I've purchased SD Cards, cables, and now this carrying case, and I must say AmazonBasics is a GREAT VALUE!This case is well fitted for my WD portable drive, has a very rigid shell, the zipper seems quite sturdy and should last, and the inside pocket is perfect for holding my USB cord.  What else could I ask for??? Nothing 

Question: Where do I get a strong zipper?
