Note that under EU law, the two year warranty must be honoured by the seller, not the manufacturer. In this case, it is Amazon that must honour the EU law if you want to try that route. When dealing with Oculus direct, you will only have the warranty they deign to give you - you didn't buy it from them. Oculus will have warranty/repair agreements with their sellers. It is usually best to go via the seller rather than the manufacturer in the EU (and don't be palmed off by the seller - it is always their responsibility to resolve warranty issues if you are a consumer).
On another note, I only just bought a Rift, and compared to the Vive (which I also had) it does seem inferior quality. However, it is lighter and the optics are noticeably better, in my opinion. I sold the Vive on after a short while playing with it. The Oculus will be staying, so I hope that it proves to be more robust than yours, Alec.
