Iam using the lenovo A7000 from 8 months.main features like design, sound reception are really good, but iam completely disappointed by the very High radiation values of this mobile phone, cant able to make the call continues for 30 minutes because we will feel heating effect and Headache from the phone.For this range of price, this phone is ok but still company needs to update the SAR values of the phone since it is very harmfull for the customers
