1) very light
2) Long autonomy 7 days for me
3) Dual Sim
4) works with all operators
negative:
1) hard post to write, you just put each sms abc mode by pressing the pound key
2) one ring that is crap, take micro card to have more tones
3) Adjustment complex volume
4) a little short length charger
for less than 20 euros I am satisfied anyway, I suggest you take the phone + mic pack card.
