Lenovo G50 70 is the good laptop.The processor core i3 makes it smoother for any operations. The worst problem is battery backup.It works hardly upto three hours and comparatively slightly heavy also. With windows it works best and sound is best.If the product battery life is extended then it works very well.It not gets very hot while working for very long time.Game play is also very smooth and heavy works also done very fast.For the use of entertainment and work both the satisfy by this laptop.Watching movies and playing games is very nice experience on this.The Lenovo has very quality sound and I always praise for it
