dont think the failing after a few months is as common as it once was , if I did I wouldent have got one my self.
I just put it down to some drives will fail, who ever makes them and F1's are selling more than most, so you hear of more of them failing.
That and if your looking to buy some thing, you look in to it, the more you look the more you see.
To many good reports not to give one ago,
