Lenovo Z50 provides great feature. it has a full hd display with intel i7 processor and nvidia geforce graphics. battery on full charge lasts upto 4.5-5 hours on continuous usage. It comes with the latest windows 10 pre loaded which offers free updates from microsoft. it is a reliable product but it is high priced laptop. There are many laptops in the market with similar features available at lower prices. one of the drawbacks of this laptop is the inbuilt speakers which have a low volume output. You need to struggle a bit to listen to the audio being played in the laptop in a bit noisy surroundings.
