I have been using this laptop from the past 1 year and it has been a very very very good experience. Talking about battery life, it lasts 5 hrs on a single charge. Screen quality is also very good and the colours are vivid and bright.
Processing power is adequate for day to day usage as well as heavy tasks. It is an ideal laptop for students as well as business uses. Local service support is also very good considering this is a very premium brand
