I have a cell phone for a week now and am completely satisfied. After promter delivery from Amazon. The housing is easy to open, inserting the battery and the card is easy, I any case, so had no problems. As I previously already with Sony-E. Phones have worked, had the menu without problems. It is easy to understand and to understand without guidance. But who comes eg from Nokia, have to get used as everywhere, of course, and for it to be concise operating instructions are, however, very poor. That would be my only negative point. Since I use to write the mobile phone almost exclusively for phone calls and SMS, I can say about the quality Walkman nothing. The phone is comfortable to hold, the buttons are small, but to make good the display Is very well read, particularly the slide, key lock is not necessary, everything is working properly. For anyone who needs a cell phone for that for which it was meant to me, it is mainly because of the fairly low price, a good choice. The endurance test is, of course, still pending, battery life up to now in the normal range.
