I have now about 1 year and have since 3x brought for repair times. This also included each always min. 4-6 weeks waiting period without a mobile phone, so I have effectively used it 9 months. Once even had the main part of the device to be completely replaced and Sony has then sent me a new device, but with the old battery and the old cover back. I found that the presence of all the problems I had with it is not exactly fair of Sony Ericcson, but here it's not going to the service ....
High voice I can not complain because it is 1A.
Also, I think it's really nice from design, menu navigation is also good.
A plus for me are the sports functions. I've used while jogging also frequently. They are great.
The large hood gets the device for the unreliability, since I can never be sure if it will work tomorrow and I need to Sony contractors again. But I can not give more than 2 stars.
