I like his review, but seems they have a QC issue with them.
They've improved them, they are on at least the 3rd revision. Many of the dead ones were first revisions, the ones that had a plastic shoe. Only time will tell how well the current revision holds up, but people are saying they've finally got the bugs worked out.
I hope they have got it right, I just bought one the other day, manufactured June 2011, so far it has been flawless.
