According to multiple reports, the cover's seam is literally coming apart after just a few days of usage. When one of the users went to a store asking for a replacement, the representative told him that at least two other people were having the same problem. Users from both the US and the UK have ended up with faulty Touch Covers, meaning that the issue might not be isolated to just a single defective batch.
we reported about the sound issues with the Microsoft Surface. As a side note, although the Smart Cover retails for over $100 online, it actually costs about $16 to make.
In case you happen to own a Microsoft Surface tablet too and your Smart Cover is also affected, spread the word by dropping a comment!
