Input:
I have owned this CD "wallet" for about a year and a half now. I purchased it in anticipation of my little daughter discovering my CD tower and the impending destruction that would follow.
I chose this one because at the time it had the combination of the largest capacity and the best rating. My one complaint with this product is the weak zipper broke within a month. I have a small CD wallet that holds 20-30 CDs with a zipper three times as burly as the one that came on this.
I suppose the zipper is not truly an essential part of the product, but it could be improved GREATLY by simply upgrading this one thing.
