About this unctuous text I can smile just tired - I just made this procedure. The reality is unfortunately different. Although the product was defective already at 9 months, did not want to exchange one him. The product is not recommended and the customer does not have much scope for improvement.
Conclusion: even a star is still too much - so buy elsewhere.
