Big disappointment for sustainability

Purchased in December 2013 just after acquisition of the phone.
As many obviously the right lower leg just broke.
No objective reason in my opinion:
- The phone has never been removed from the case,
- The phone never broke.
Too bad that the guarantee is limited to 1 year, otherwise for the principle, I would have asked to play.
In short, I strongly advises against and I regret this purchase.
