I bought this sheet in early October 2011.
The item arrived in good time, but I noticed one of the corner seams hadn't been machined properly. Fortunately, it was a machining error and not a tear, so I was able to un-pick and re-machine it to my satisfaction.
Although the item is described as having a 400 thread-count, I would suggest the manufacturer used a very short cotton staple, because the sheet has had very little usage and the fabric is now "pilling". It won't be too long before I have to throw it away, as I find the little cotton balls irritating to lay on.
A bit of a disappointment.
